About PP Compression Female Threaded Adapter
The PP compression female threaded adapter is used where a compatible plastic pipe must connect to a male-threaded valve, fitting, accessory or equipment connection. One side provides a mechanical compression connection for the pipe, while the other side provides a female threaded outlet.
The correct model should be selected according to both the pipe outside diameter and the required female thread size. For example, 50 × 2″ indicates a 50 mm compression pipe connection with a 2-inch female thread.
About PP Compression Fittings
PP compression fittings are mechanical pipe fittings commonly used in water distribution, agricultural irrigation, landscaping and compatible utility piping systems. Their compression-joint design allows installation without fusion welding equipment.
A typical PP compression fitting uses a body, compression nut, gripping components and sealing elements to create a mechanical connection. Product selection should consider pipe outside diameter, thread size where applicable, fitting type, fluid medium and project operating conditions.

Applications & Installation
Typical Applications
Suitable for compatible water distribution, irrigation, landscaping, agricultural and utility piping systems where a plastic pipe must connect to a male-threaded component.
Installation
Cut the pipe square, clean the pipe end and insert it into the compression side according to the fitting design. Tighten the compression nut to secure the pipe, then connect the female threaded end to the matching male-threaded component using the sealing method specified for the installation. Avoid excessive tightening.
