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.
The lighter rubber fittings may not muffle sound as well as the heavy cast-iron fittings. In addition, some conservative plumbing codes still require leaded hub joints for final connections where the sewer main leaves a building. Although low-priced wyes are often spot-welded, industrial-strength wyes are flash-welded at each seam. In long-distance pipeline applications, a specialized wye is used for allow insertion of pigging to keep pipes clear and maintain flow.
McAlpine valves, such as the McAlpine VP50P air admittance valve, features a dual-fit synthetic rubber finger seal for 3” or 4” soil pipe. Direct the flow of water outside a property with overflow pipes. Our range of PVC overflow pipes are available to buy in 30m, in either black or white. Aquaflow pipes come in a variety of sizes and shapes to complement the property design.
Fittings for central vacuum systems are similar to DWV fittings, but are usually of thinner and lighter construction because the weight of the materials conveyed is less. Vacuum-system designs share with DWV designs the need to eliminate internal ridges, burrs, sharp turns, or other obstructions which might create clogs. Non-return or check valves allow free flow of a fluid in one direction, but prevent its flow in a reverse direction. They are often seen in drainage or sewage systems, but may also be used in pressurized systems. Isolation valves are used to temporarily disconnect part of a piping system, to allow maintenance or repair, for example.
In a long radius elbow, the centreline radius is 1.5 times the nominal size of the pipe or you can say 1.5 times the diameter of the pipe. Normally long radius elbows are used in piping as pressure loss is less as compared to short radius elbow. Elbows are available in two radius types, Short radius and Long Radius (1.5D).
Stainless steel and carbon steel press fittings can hold up to 16 bars of pressure. Many companies and individuals use the abbreviation IPS which normally refers to iron pipe size. When we use the term ‘IPS-sized’, or either Mips or Fips , we are referring to pipes with NPT threads.
For further information about how the law determines what is “lead free”, rules regarding which plumbing products must be “lead free”, and who these laws will affect, please click here. This video demonstrates how to easily install end of line fittings using the Fig. At Toolstation we can help you find the perfect plumbing fittings and components so that you can carry out safe and effective plumbing – whatever you’re working on. We stock leading brands that you can trust like Speedfit by John Guest and Cuprofit from Conex Bänninger so you can fit with confidence. Check that the cutting ring is positioned and seated correctly, and that the shoulder of cut material is present. However, in order to function properly our fittings must have been assembled in strict compliance with the assembly inst- ructions supplied by us.
Pipe Fittings are Piping component that helps in Changes the direction of the flow such as elbows, tees. Changes the size of the pipe such as reducers, reducing tees. Connect different components such as couplings and stop the flows such as Caps.
It should be noted that this safety factor is contingent on error-free assembly and correct routing of the pipeline system. Information about ttings often includes the nominal pressure, designated PN. The nominal pressure, PN, is merely an index that serves as an identi er or designator for a part or system. When the assembly instructions are followed, repeat ttings can be carried out safely and reliably.
Half Coupling is used for small bore branching from a vessel or large pipe. Returning elbows are used to make a 180º change in direction. Returns are used in the heating coil, heat exchanger, tank vent, etc. These Fittings are available in a different types of end connections. And when you need to test the pressure of your pipes, our selection of test plugs proves to be a reliable option. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be “essentially lead free” (less than 0.25% weighted average).
Long elbows are used in low-pressure gravity-fed systems and other applications where low turbulence and minimum deposition of entrained solids are of concern. They are available in acrylonitrile butadiene styrene , polyvinyl chloride , chlorinated polyvinyl chloride , and copper, and are used in DWV systems, sewage, and central vacuum systems. This section discusses fittings primarily used in pressurized piping systems, though there is some overlap with fittings for low-pressure or non-pressurized systems. Specialized fittings for the latter setups are discussed in the next major subsection.

Although reducers are usually concentric, eccentric reducers are used as needed to maintain the top- or bottom-of-pipe level. Gaskets are mechanical seals, usually ring-shaped, which seal flange joints. Commonly used gaskets are non-metallic (ASME B 16.21), spiral-wound (ASME B 16.20) and ring-joint (ASME B 16.20). Non-metallic gaskets are used with flat- or raised-face flanges. Spiral-wound gaskets are used with raised-face flanges, and ring-joint gaskets are used with ring-type joint flanges. Stress develops between an RTJ gasket and the flange groove when the gasket is bolted to a flange, leading to plastic deformation of the gasket.
Isolation valves are typically left in either a fully open or fully closed position. A given isolation valve may be in place for many years without being operated, but must be designed to be readily operable whenever needed, including emergency use. Since the alignment stop is missing, it is up to the installer to carefully measure the final location of the slip coupling to ensure that it is located correctly. If there’s a pipe needing cut or bent, we have the equipment to help make it happen.
The ends may be machined for butt welding, threaded , or socketed. When the ends differ in size, it is known as a reducing elbow. From dependable compression fittings to soldier rings and press-fit elbows, our range of pipe fittings helps make sure you can finish the job properly.
