Investment Casting Stainless Steel Pipe End Caps Have Female Thread

A threaded cap is a fitting that is designed to cover the ends of the piping system. These caps ensure a waterproof connection. The threaded cap fitting can also be used to close the ends of pneumatic pipes, tubes, or hydraulic systems. The versatile threaded pipe cap provides protection to the pipes against corrosive effluents that are common in harsh environments.

The threads on these caps are female. The thread, commonly known as an NPT, can be straight or tapered. Often, plugs have a male thread, whereas caps often have a female thread. Male threads are on the outside of a fitting and screw into the female threads, then use PTFE tape to secure the seal.

The threaded end cap is easy to install and doesn’t require special machinery to torque them. These caps don’t even have higher torque demands to bind them in place. The screw cap fittings are preferred for use in lower pressure and temperature condition where stress on the system is low. Threaded Pipe Caps assist in resisting repeated tightening cycles that cause threads to loosen during drilling. The Stainless Steel Threaded Pipe Cap has to be fitted with enough space for future cutting and joining of other fittings if necessary.

A stainless steel threaded cap has reliable corrosion resistance properties and works well in high-temperature conditions. Taper-tapped threads seal better than straight-tapped thread at the same cost. The design is for lower-pressure applications in Natural Gas, Oil, Steam, Water, and Air piping systems.
