Push-to-pull fittings are a type of easily removed compression fitting that allows pipes to be connected with minimal use of tools. These fittings are similar to regular compression fittings, but use an O-ring for sealing and a grip ring to hold the pipe. The main advantage is that it can easily be removed and re-used, it is easy to assemble, and the joints are still rotatable even after assembly. The pipe end should be square so it sits against the stop in the fittings and does not create turbulence, and needs to be a clean cut to avoid damaging the O-ring during insertion.
Precautions must also be taken to avoid starting fires caused by stray sparks and hot welding debris. Central vacuum system inlet fittings are intentionally designed with a tighter radius of curvature than those of other bends in the system. If vacuumed debris becomes stuck it will jam at the inlet, where it is easy to find and remove. A double-tapped bushing is more compact than a reducer, but not as flexible. While a double-tapped bushing has a smaller female thread concentric to a larger male thread , a reducer may have large and small ends of either gender.
Flanges used in piping (orifice, threaded, slip-on, blind, weld neck, socket, lap-joint, and reducing) are available with a variety of facings, such as raised, flat, and ring-joint. A barb , which connects flexible hose or tubing to pipes, typically has a male-threaded end which mates with female threads. The other end of the fitting has a single- or multi-barbed tube—a long tapered cone with ridges, which is inserted into a flexible hose. The nipple is a short stub of a pipe that has a male pipe thread at each end or at one end. The swage is like reducers but small in size and used to connect pipes to smaller screwed or socket welded pipes. Like reducers, they are also available in concentric & eccentric types.
Elbows are generally available with an angle of 22.5o, 45o and 90o. If pipes are of same diameter then normal elbows are used otherwise Reducer elbows are used. These are generally coming with female threads and we can fix them by butt or socket welding also. Obviously, pipe fittings are attached to the end of pipes that allow them to change direction, control the flow, and change the diameter of the pipe. Being a non-trivial part of plumbing and piping systems, consulting us with your need is definitely advised to save yourself time, money, materials, and headaches. Unions are used as an alternative to flanges connection in low-pressure small bore piping where the dismantling of the pipe is required more often.
Pipe fitting product line includes a large number of fitting types that surpass the requirements of this standard. In these special forms, e.g., pipe fittings with spring-back tolerances, the connector dimensions have been adapted to the pertinent standard, so that they can be replaced at any time. There are various pipe fittings available, each with their own unique function. The materials used in plumbing has changed over the years so we’ve made sure that we offer a comprehensive enough range to cater for both old and new installations. You’ll find pipe fittings from leading brands like JG Speedfit, Plumbsure and Fluidmaster that cover a wide range of fitting types. A nipple is a short stub of pipe, usually male-threaded steel, brass, chlorinated polyvinyl chloride , or copper , which connects two other fittings.

Tighten the union nut until the point at which it becomes noticeably more di cult to turn the union nut. At this point, for example, minor damage on the thread caused by the union nut getting caught must be overcome.
The larger-diameter hub was also called a “bell” because of its shape. Adequate ventilation is essential to remove metal fumes from welding operations, and personal protective equipment must be worn. Because the high temperatures during welding can often generate intense ultraviolet light, dark goggles or full face shields must be used to protect the eyes.
Union is a type of fitting, which functions as similar to coupling. But coupling cannot be removed after fixing but in this case we can remove the union whenever we needed. Although compression connections are less durable than soldered connections, they are easy to install with simple tools. However, they take longer to install than soldered joints and sometimes require re-tightening to stop slow leaks which may develop over time. Because of this possible leakage, they are generally restricted to accessible locations , and are prohibited in concealed locations such as the interiors of walls.
