How To Identify Fitting Threads

We are frequently asked to explain the differences in various types of threads, as piping specifications and (or) equipment are designed with the following threaded connections:

1. NPT
2. BSPT
3. BSPP
4. Screw Thread
5. S.A.E. Straight Thread
6. Metric Thread

 

NPT Thread

 

NPT, National Pipe Thread or pipe taper is the most commonly used pipe thread in the United States and Canada.

 

Figure 1 NPT (National Pipe Taper)

Characteristics of NPT

1. Thread Pitch measured in inches.
2. Root & Crest Truncation are flat.
3. 60° Thread Angle
4. Taper Angle 1° 47’

 

Parker’s Instrumentation Products Division machines this thread on all CPI™, A-LOK® as well as on pipe & pipe adapter fittings where N.P.T. is designated. All male threads are rolled for strength and durability. Parker IPD’s NPT threads meet the standards set forth by ANSI B 1.20.1  

BSPT - British Standard Taper

Figure 2 BSPT

  

Characteristics of BSPT

1. Taper Angle 1° 47’
2. 55° thread angle
3. Pitch can be measured in millimeters or inches
4. Thread truncation is round
5. BSPT threads are different from and will not substitute for N.P.T.
6. threads.

 
The following standards are equivalent to B.S.P.T.

• ISO 7/1 (International Standards Organization)
• DIN 2999 (Deutsche Industrial Norme)
• JIS B0203 (Japanese Industrial Standard)
• d. BS 21 British Standard

BSPP - British Standard Parallel Pipe
 

Form A
A self centering taper is used at the hex which centers a “Bonded” washer (usually metal and elastomer) to seal to the surface surrounding the female thread.

Form B
A metal gasket (usually copper) performs the

seal between the face of the body and the face of the female threaded component. For Form “B” replace “R” in P/N with “BR”.

 

Characteristics of BSPP

1. 55° thread angle
2. Thread pitch measured in inches
3. Thread diameter measured in inches
4. Root/Crest Truncation round

 

A parallel thread form uses the threads for holding power only and seals by means of an O-ring and retainer ring.

 

The following standards are equivalent to B.S.P.P.

1. ISO 228/1 (International Standards Organization)
2. DIN 3852 Part 2 & Parallel threads (Deutsche Industrial Norme)
3. JIS B0202 (Japanese Industrial Standard)
4. BS 2779 (British Standard)

 

Unified Screw Threads

These are very common threads utilized on valves and fitting stems, nut and fitting end threads. They are straight, NOT tapered threads used for holding power.

 

Figure 4

 

Screw threads are denoted by the following:
For instance: 5/16                -          20
                      Thread Diameter       Number of Threads per inch

 

In general - screw threads can be further classified into various types of pitch’ (UNF) Unified Fine Pitch - (UNC) Unified Coarse - (UN) Unified Constant.

 

These classifications are determined by the relationship of threads per inch to outer diameter.

 

Note: For further information on thread pitch, please refer to ISO standards handbook or H-28 handbook.

 

SAE Straight Thread Port (SAE J1926)

 

Parker straight thread fittings shown are for connection with the SAE straight thread port as shown here. Basic port dimensions are give in Fig. 5 below. This port is the same as MS16142. It is also similar to, but dimensionally not the same as MS 33649 and AND 10050.

 

 

Figure 5 SAE Straight Thread O-ring Port Dimensions

 

 

NOTE: Tap drill lengths “P” given here require bottoming taps. Increase “P” as required for standard taps.

 

NOTE: Diameter “U” shall be concentric with thread pitch diameter within .005 FIM. It should be free from longitudinal and spiral tool marks.

 

Metric Threads (ISO 6149-2)

The following sections were prepared with the intention of explaining that NONE of them should be confused with a metric thread.

 

Please remember that a metric thread, be it parallel or tapered is designated as metric by the distance in millimeters from thread crest to crest. In the case of the parallel thread Figure 6 the O.D. is also expressed in millimeters.

 

Figure 6

 

To assist you in determining the various types of threads, Parker has available the International Thread I.D. Kit/Bulletin 4303-B1. It includes calipers, international and screw thread pitch gauges.

Parker Balston Membrane Compressed Air Dryers Exemption from EU ATEX Directive

Parker Balston Membrane Compressed Air Dryers Receive Exemption from EU ATEX Directive

Haverhill, MA, May 21, 2012 - The Filtration and Separation Division of Parker Hannifin Corporation, the global leader in motion and control technologies, is pleased to announce that Parker Balston Membrane Compressed Air Dryers are exempt from the EU ATEX Directive.

According to the Hazardous Locations Product Team of CSA International, “The Membrane Dryer products are not required to meet the EU ATEX Directive. The product is non-electrical with no moving mechanical components. The air movement within the product is not likely to produce static as an ignition hazard…There is not enough energy around to cause an ignition.”

Parker Balston Membrane Air Dryers offer the unique ability to lower a compressed air stream’s dewpoint without electricity or moving parts permitting use in flammable and hazardous environments where explosions or fires are a concern.

The drying system produces a dewpoint of -40°F (-40°C) and lower while removing all other compressed air contaminants 0.01 micron in size and larger. The system utilizes sophisticated technology to dehydrate the air without the need of electricity. The wall mountable air dryers can be easily configured and are ideal for space constrained. Unsurpassed in performance and durability to dehydrate and purify compressed air, Parker Balston Membrane Air Dryers significantly outperform conventional air filtration. Prefilters, membrane, modules and mounting brackets are included with the system.

Parker Fitting Assembly & Remake Instructions

1. Parker instrument tube fittings are sold completely assembled and ready for immediate use. Simply insert the tube as illustrated until it bottoms in the fitting body. (If the fitting is disassembled, note that the small tapered end of the ferrule(s) go into the fitting body.)

2. Tighten nut finger tight. Then tighten nut with wrench an additional 3/4 or 1-1/4 turns indicated at left. Hold Parker fitting body with a second wrench to prevent body from turning. It is helpful to mark the nut to facilitate counting the number of turns.

For maximum number of remakes, mark the Parker fitting and nut before disassembly. Before retightening, make sure the assembly has been inserted into the fitting until the ferrule seats in the fitting. Retighten the nut by hand. Rotate the nut with a wrench to the original position as indicated by the previous marks lining up. (A noticeable increase in mechanical resistance will be felt indicating the ferrule is being re-sprung into sealing position.)

Only after several remakes will it become necessary to advance the nut slightly past the original position. This advance (indicated by B) need only be 10° - 20° (less than 1/3 of a hex flat).

Parker A-Lok/CPI® Tube Fitting part numbers use symbols to identify the size, style, and material. Tube and pipe thread sizes begin with a number indicating their size in sixteenths of an inch. For example, 4=4/16” or 1/4”; 16=16/16” or 1".

NOTE: Lubrication on the nut is REQUIRED for proper assemblyon all LARGER size fittings in both inch and metric sizes.  This requirement applies to:

• inch sizes of 20 and higher
• metric sizes of 25 and higher

Gaugeability Instructions*

1. From “finger tight” position, wrench 1-1/4 turns for 1/4" to 1" size fittings (6mm to 25mm) (1/16", 1/8", 3/16", 2mm, 3mm and 4mm size tube fittings only wrench 3/4 turn from finger tight position). Hold fitting body hex with second wrench to prevent body from turning as you tighten. It is a good idea to mark the nut (scribe or ink) to help you count the turns.

2. Now select the proper size inspection gauge and try to place it, as shown, between the nut and the body hex. If gauge DOES NOT FIT AT ANY POINT between them, you have correctly tightened the nut. If you can slip the gauge into the space, the fitting is not properly made up, and you must repeat the assembly procedure.

*For initial make up only.

Advantages of Parker CPI Single Ferrule Instrumentation Tube Fittings vs Swagelok type

Advantages of Parker CPI single ferrule instrumentation tube fittings over dual ferrule (Swagelok - type) tube fittings.

Safety - By reducing chances for error, chances for leaks are reduced.

• There are 13 incorrect configurations of a two-ferrule instrument tube fitting like (Swagelok).




• There are only 2 incorrect configurations of a Parker CPI single-ferrule tube fitting.




• Parker CPI single-ferrule fittings move a key sealing point in front of the tube grip point. This greatly reduces potential problems from vibration and thermo-cycling versus the two-ferrule instrument tube fitting design.

Simplicity - By design, Parker CPI single ferrule tube fittings are easier to work with than dual-ferrule instrumentation tube fittings like (Swagelok).

• Less torque is required to install single-ferrule Parker CPI fittings than two-ferrule instrument tube fittings.




• With single-ferrule Parker CPI there are fewer components to stock, re-order, and carry around the plant.

Service Life - The Parker CPI moly-impregnated stainless steel nut provides more remakes and less thread galling versus silver coated threads used in two-ferrule designs like (Swagelok).

Interchangeability - Parker CPI single-ferrules are fully interchangeable with Swagelok dual-ferrule systems and can be used in either Parker or Swagelok fitting bodies.
