Brass CPVC and PPR Inserts

Brass CPVC and PPR Inserts are metal components incorporated into plastic pipe fittings to create threaded connection points. They are available in male and female configurations, allowing plastic fittings to connect with compatible threaded plumbing components. The outer surface may feature straight, cross or diamond knurling, which helps anchor the insert within the surrounding plastic during fitting manufacture. The internal thread and external profile are selected according to the fitting design and assembly requirements.

Product Features

01 / THREAD TYPE Male and Female Inserts

Male-threaded versions provide an external threaded connection, while female inserts accommodate compatible externally threaded components.

02 / OUTER PROFILE Knurled Retention Surface

Straight, cross or diamond knurling can help the insert grip the surrounding plastic within the completed fitting.

03 / THREADING Threaded Connection Interface

The internal or external thread profile is selected to match the mating component and required connection specification.

04 / FITTING DESIGN Insert-to-Mould Compatibility

The insert's outside diameter, length and retention profile are matched to the plastic fitting's mould design.

Applications

These inserts are used in the manufacture of CPVC and PPR plumbing fittings, including threaded adaptors, connector fittings and other moulded components that require a metal threaded interface. They allow plastic piping systems to connect with compatible metal-threaded plumbing parts without relying on a thread formed directly in the plastic.

The appropriate insert depends on the fitting design, male or female thread arrangement, required thread standard and mould dimensions. Insert geometry and knurling should be selected to suit the intended plastic fitting and its manufacturing process.
