What is a Npsm fitting?
What is a Npsm fitting?
National pip straight mechanical (NPSM) fittings are female swivel fittings with a straight thread and a 30° cone and form a mechanical seal when mated with NPTF male fittings. NPSM fittings were designed to eliminate hose stress from twisting during assembly and to reduce to number of hose fittings required.
What is Npsm hose?
PIPE & TUBING NPSM (National Pipe Straight Mechanical) are female swivel pipe fittings with a straight thread and a 30 degree cone. When used with a male fitting, a mechanical seal is formed.
Is Npsm the same as FIP?
An equivalent designation is MIP (Male iron pipe) and FIP (Female iron pipe). Also the terms NPS and NPSM are sometimes used to designate a straight, not tapered, thread. (This should not be confused with NPS meaning Nominal Pipe Size.)
What is Npsm thread size?
NPSM Pipe Thread ANSI B 1.20. 1-1983 (R1992)
| Nominal Diameter | Major Diameter mm | Major Diameter Inch |
|---|---|---|
| 1/4″ – 18 NPSM | 13.716 | 0.540 |
| 3/8″ – 18 NPSM | 17.145 | 0.675 |
| 1/2″ – 14 NPSM | 21.336 | 0.840 |

What kind of thread is Npsm?
NPT is the abbreviation for National Pipe Thread Tapered, which is the U.S. standard for tapered threads used to join pipes and fittings. They were established as a standard by the American National Standard Pipe Thread, commonly referred to as the national pipe thread standards.
Does NPT fit Npsm?
A female NPSM connection can accept either an NPT or NPS (American National Standard Pipe Straight thread) measuring instrumentation.
Is Npsm thread compatible with NPT?
Is Npsm same as NPT?
NPSM is NATIONAL PIPE STRAIGHT MECHANICAL thread standard ANSI/ASME B1. 20.1 , NPT is National Standard Taper Pipe Threads ANSI B1. 20.1, NPTF is National Pipe Thread Fuel standards ANSI B 1.20. 3, BSPT is British Standard Pipe Taper thread AS 1722.1, BS 21, ISO 7, these are different thread standards.
Can I connect FIP to NPT?
Most pipe thread types are not interchangeable. NPT, MIP, and FIP work together but do not mate with any other types. An NPT will not fit a BSP. Many times, the fitting itself will tell you what thread type you need.
What is a 1/2 Npsm thread?
1 2. NPSM stands for National Pipe Straight Mechanical. Also known as “NPS”, NPSM threads are a standard pipe thread that is not tapered.
