Threaded Pipe Fittings

Buy cut lengths of welded & seamless stainless steel pipe online in Sch 10, Sch 40, Sch 80, and Sch 160. Crimped or pressed connections use special fittings which are permanently attached to tubing with a powered crimper. The fittings, manufactured with a pre-installed sealant or O-ring, slide over the tubing to be connected. High pressure is used to deform the fitting and compress the sealant against the inner tubing, creating a leakproof seal. Flange connections tend to be expensive, because of their requirement for precision forming of metal. To make a solder connection, a chemical flux is applied to the inner sleeve of a joint and the pipe is inserted.

Hydraulic fittings are designed and constructed to resist high-pressure leakage and sudden failure. The diverter tee is designed to allow flow to continue in the main line, even when the side branch is shut down and not calling for heat. Diverter tees have directional markings which must be heeded; a tee installed backwards will function very poorly.

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.

If both ends are the same gender, it is a gender-changing reducer. Insulating pipes is important when you’re working with refrigeration and heating systems. We stock Class O, plumbing pipe and lagging to help with insulation in all scenarios. In Eccentric reducer, the center of both ends is on different axis as shown in the image. When one of the outside surfaces of the pipeline is to be maintained the same, eccentric reducers are required. It is a type of Tee that has the branch at a 45° angle, or an angle other than 90°.

Fittings require money, time, materials, and tools to install, and are an important part of piping and plumbing systems. Valves are technically fittings, but are usually discussed separately. Choosing the material of your pipe fitting comes down to what will be running through the pipe. From fittings perfect for cold water supplies to reliable options for gases and chemicals wastes, we carry a variety of fitting options to help you get the job done.

A specially shaped limit ridge prevents overtightening, the pipe material that is raised in front of the edges is cold-hardened. Our team’s focus is to provide the solutions you need to succeed and grow. This included adding products based on items you are searching for, offering rewards for your purchases & business advantage memberships with discounts built into your online account.

Oil the thread of the union nut, the cutting ring and the screw sleeve thread. In these threaded connections, the cutting ring has been pre-assembled by the manufacturer. The sealing cone is fitted with an O-ring and is shaped so as to fit precisely inside the mating part of the threaded connector. Although flare connections are labor-intensive, they are durable and reliable. Considered more secure against leaks and sudden failure, they are used in hydraulic brake systems, and in other high-pressure, high-reliability applications. Properly welded joints are considered reliable and durable.

They are used to connect pipework together and form angles. Plumbing fittings come in various different types to reduce the flow size from larger to smaller or to change the direction of flow between two pieces of pipework. Choose from metal or plastic fittings and various pack sizes.

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.
