Cap

Pipe caps act as protective device and are designed to protect pipe ends of various shapes. The main purpose of using pipe caps is to waterproof the connections. They are also used to close the the ends of hydraulic or pneumatic pipes and tubes. They are used in the plumbing apparatus of domestic, commercial and industrial water supply lines, machinery and processing equipment etc. They are also fitted on water pump lines with the sole purpose of removing air blocks. Pipe caps are highly demanded as an important category of pipe fittings.

Types of pipe caps:

Pipe caps come in many different types and the type vary according to the application. However pipe caps also vary depending on their construction features and it is very important for the buyer to know the right type of pipe cap. Based on construction, pipe caps are of the following types:

Threaded Caps:
These caps are female threaded. The thread can be either straight or tapered, also referred as NPT. Generally, caps have a female thread and plugs have a male thread.

Tapered Caps:
These caps have tapered sides, which offers a close fit. Some of these fittings can be used either as a cap or a plug. Tapered caps and plugs are multi-functional and go well with male and female NPT threads, straight tubes and bars; and male straight threads. These fittings have a tapered body to provide a secure and firm friction fit while facilitating easy removal. The tapered caps are designed to provide protection for all internal and external, threaded and non-threaded fittings against damage, dirt or moisture that can occur.

Anti-roll Caps:
These caps are round in shape with a slightly square end. This prevents pipes and tubes from rolling.
