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.

Cast iron piping was traditionally made with one “spigot” end and one “socket” or “hub” end (cup-shaped).

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.

Lightly lubricate the thread and cone of the assembly stud and the thread of the union nut. However, the O-ring must be removed before welding, and any stray welding material must be removed from the O-ring groove and the fitting hole. Plug is a component of plumbing component which is generally used to close pipe opening during inspections and repairs. In use, the spigot of one segment was placed into the socket of the preceding one and a ring of oakum was forced down into the joint with a caulking iron. Ideally, this would be done by pouring in molten lead, allowing it to set, and hammering it tightly with a caulking tool. If this was not possible due to position or some other constraint, the joint could alternatively be filled with lead wool or rope, which was forcibly compacted one layer at a time.

This view looking upwards through a hole in the ceiling shows a traditional leaded hub joint and a more recent rubber-sleeved hubless connection . There are similar fittings for both sweat and solvent joinery. Since they are not “tapped” , they are simply called reducing bushings. 3000 & 6000 class fittings are available in both Threaded and Socket Weld types.

Short radius elbows are used under limited space applications. However, it has a high-pressure drop due to a sudden change in the direction of flow. The 90 reducing elbow is designed to change direction as well as reduce the size of the pipe within a piping system. The reducing elbow eliminates one pipe fitting and reduces the welding by more than one-third. Also, the gradual reduction in diameter throughout the arc of the reducing elbow provides lower resistance to flow and reduces the effect of stream turbulence and potential internal erosion. These features prevent sizeable pressure drops in the line.

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.
