Key Features

Threaded Transition: The HDPE female threaded coupler connects PE100 pipe directly to male-threaded valves, meters and metal fittings.
Precision Thread Form: Threads of the HDPE female threaded coupler are molded to standard pipe thread profiles for a tight, sealant-friendly fit.
PE100 High-Strength Material: Every HDPE female threaded coupler is molded from virgin PE100 compound rated for a 50-year design life.
Reinforced Thread Zone: Extra wall section behind the thread gives the HDPE female threaded coupler full PN10 - PN16 pressure capacity.
Nine Size Steps: The HDPE female threaded coupler covers 20 - 110 mm, matching 1/2" through 4" male threads.
Corrosion-Free Service: Unlike brass adapters, the HDPE female threaded coupler never corrodes or seizes, allowing future disassembly.

Production

Raw Material

The HDPE female threaded coupler is molded from certified PE100 black compound with uniform carbon black dispersion, meeting ISO 4427 and EN 12201.

Molding Process

Injection molding forms the HDPE female threaded coupler around threaded cores that reproduce the full thread profile without secondary machining.

Quality Control

Batches of HDPE female threaded coupler fittings are checked with thread go/no-go gauges and gauged for wall thickness, then sampled for hydrostatic strength per ISO 1167.

Applications

Service connections use the HDPE female threaded coupler to join PE100 lines to metal stop valves and meters.
Pump and equipment nozzles rely on the HDPE female threaded coupler for a corrosion-free threaded transition.
Irrigation systems install the HDPE female threaded coupler to connect risers and sprinkler manifolds.
Building water entries choose the HDPE female threaded coupler where PE100 service meets indoor metal plumbing.
