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.
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.
Lightly oil the cone of the screw sleeve and the thread of the union nut. With sealing cone screw-on fittings with O-ring (AOL / AOS), the pre-stressing of the O-ring must be bridged and the sealing cone must lie metallically flush against the cone of the HL/HS connector. At this point, the cutting ring may be allowed to rotate, but must not move axially. Tightening torques for stainless steel fittings and for fittings with UN/UNF threads available upon request. The entire fitting consists of the threaded connector, the spacer ring with O-ring seal, the pressure ring and the union nut.
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.
Quality GroovJoint fittings carry approvals by UL, ULC, and NSF-61. Flexible fittings may also be used to reduce transmission of vibration into the DWV system. Although the fittings are not cheap, they are reasonably durable .
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.
Wye tee allows one pipe to be joined to another at a 45° angle. This type of tee reduces friction and turbulence that could hamper the flow. A barred tee which is also known as a scrapper tee is used in pipelines that are pigged. The branch of the tee has a restriction bar welded internally to prevent the pig or scrapper to enter the branch. The bars are welded in the branch in a way that it will allow restriction free passage of the pig from the run pipe.
It must be installed in an easily accessible place for adjustment, replacement, and repair. A trap primer, a specialized valve, is usually connected to a clean-water supply in addition to a DWV system. Because of the dual connection, it must be designed to resist the accidental backflow of contaminated water. Underground piping systems for landscaping drainage or the disposal of stormwater or groundwater also use low-pressure gravity flow, so fittings for these systems resemble larger-scale DWV fittings.
Throttling valves are used to control the amount or pressure of a fluid allowed to pass through, and are designed to withstand the stress and wear caused by this type of operation. A double-tapped bushing is a fitting which serves as a reducer. It is a sleeve similar to a close nipple, but is threaded on both its inner and outer circumferences. Like a reducer, a double-tapped bushing has two threads of different sizes.
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.
A specially shaped limit ridge prevents overtightening, the pipe material that is raised in front of the edges is cold-hardened.
