The types are named with a full name and an abbreviation, such as NPT, NPS, NPTF, or NPSC. MIP is an abbreviation for male iron pipe, and FIP is an abbreviation for female iron pipe. [2] Outside North America, some US pipe thread sizes are widely used, as well as many British Standard Pipe threads and ISO 7–1, 7–2, 228–1, and 228-2 threads.
JIC hydraulic fitting from 1967 Ford backhoe. It was badly stuck, but shows what a JIC fitting looks like. The left is the male part, the right is female. A JIC bulkhead adapter, which converts National Pipe Thread (NPT) on the left to JIC on the right. The angled seating surface is clearly visible on the far right.
Alternatively it is a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female British standard pipe threads. If the two ends of a coupling are of different standards or joining methods, the coupling is called an adapter. Examples ...
Piping or tubing is usually inserted into fittings to make connections. Connectors are assigned a gender, abbreviated M or F. An example of this is a "3 ⁄ 4-inch female adapter NPT", which would have a corresponding male connection of the same size and thread standard (in this case also NPT).
The cams at the end of each lever on the female end align with a circumferential groove on the male end. When the levers are rotated to the locked position, they pull the male end into the female socket, creating a tight seal against a gasket within the female socket. The arms lock into position using over-center geometry, preventing accidental ...
Schematic symbols for male and female connector pins. In electrical and mechanical trades and manufacturing, each half of a pair of mating connectors or fasteners is conventionally designated as male or female, [1] a distinction referred to as its gender. [2] The female connector is generally a receptacle that receives and holds the male connector.
PTFE tape used for different sized fittings PTFE tape for natural gas. There are two US standards for determining the quality of any thread seal tape. MIL-T-27730A (an obsolete military specification still commonly used in industry in the US) requires a minimum thickness of 3.5 mils and a minimum PTFE purity of 99%. [3]
(In Europe, taper female pipe threads are not commonly used.) Longscrew threads These are parallel pipe threads used where a pressure-tight joint is achieved by the compression of a soft material (such as an o-ring seal or a washer) between the end face of the male thread and a socket or nipple face, with the tightening of a backnut.
