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.
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.
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.
“plumbing – How do I make my bathroom pipes more practical? – Home Improvement Stack Exchange”. This is also an indication that a clean-out fitting could be installed to provide easier future access. Cast iron piping was traditionally made with one “spigot” end and one “socket” or “hub” end (cup-shaped).
The joint is then heated, typically by using a propane or MAPP gas torch, although electrically heated soldering tools are sometimes used. Once the fitting and pipe have reached sufficient temperature, solder is applied to the heated joint, and the molten solder is drawn into the joint by capillary action as the flux vaporizes. “Sweating” is a term sometimes used to describe the soldering of pipe joints. Assembling threaded pipe is labor-intensive, and requires skill and planning to allow lengths of pipe to be screwed together in sequence. Most threaded-pipe systems require the use of strategically located pipe-union fittings in final assembly. Threaded pipe is heavy, and requires adequate attachment to support its weight.
This generally requires that the piping and fitting are the same material. Skill is required to melt the joint sufficiently to ensure good fusion, while not deforming or damaging the pieces being joined. A trap primer automatically injects water into a trap, maintaining a water seal to keep sewer gas out of buildings.
Our goal is to help make purchasing quick with fewer shipping costs and less time spent scouring the web for the pipe fittings you need. Tee type fitting is a component of plumbing system which is in T-shape. It is having one inlet and two outlets, outlets are arranged at 90o to the main line connection . It can also be used to combine the flow from two inlets to one outlet. They are also available in different materials and different sizes.
A galvanized coating of metallic zinc was often used to protect steel water pipes from corrosion, but this protective coating eventually would dissolve away, exposing the iron to deterioration. Pipes used to convey fuel gas are often made of “black iron”, which has been chemically treated to reduce corrosion, but this treatment does not resist erosion from flowing water. Hydraulic systems use high fluid pressure, such as the hydraulic actuators for bulldozers and backhoes. Their hydraulic fittings are designed and rated for much greater pressure than that experienced in general piping systems, and they are generally not compatible with those used in plumbing.
