HDPE Butt Fusion Fittings

Product Overview

HDPE end cap manufactured from PE100 for pipeline termination and sealing. This HDPE butt fusion end cap permanently closes the end of a PE100 line with a full-pressure-rated weld, and can be cut off later for network extension. The HDPE butt fusion end cap covers an extra-wide OD 75 - 1200 mm range in PN10 - PN25 ratings per ISO 4427.

Key Features

Pressure-Rated Seal: The HDPE butt fusion end cap carries the same pressure class as the pipe, holding full line pressure at the dead end.
Dished Head Design: The domed profile of the HDPE butt fusion end cap distributes end-thrust stress evenly across the cap.
PE100 High-Strength Material: Every HDPE butt fusion end cap is molded from virgin PE100 compound rated for a 50-year design life.
Full-Strength Fusion Joint: The HDPE butt fusion end cap welds with standard butt fusion machines for a permanent, leak-free closure.
Wide OD 75 - 1200 mm Range: The HDPE butt fusion end cap covers distribution lines through large transmission mains up to PN25.
Corrosion-Free Service: The HDPE butt fusion end cap never rusts or degrades in soil, giving decades of maintenance-free sealing.

Production

Raw Material

Each HDPE butt fusion end cap is molded from certified PE100 black compound with uniform carbon black dispersion, compliant with ISO 4427 and EN 12201.

Molding Process

The HDPE butt fusion end cap is injection molded with domed cores sized to keep wall thickness uniform across the head, with large sizes CNC machined for accuracy.

Quality Control

Batches of HDPE butt fusion end cap fittings are gauged for end diameter, head thickness and ovality, then sampled for hydrostatic strength per ISO 1167.

Applications

Dead-end mains use the HDPE butt fusion end cap to terminate lines that will be extended later.
Pressure testing crews install the HDPE butt fusion end cap to close off sections during hydrostatic tests.
Staged construction projects rely on the HDPE butt fusion end cap to seal phase boundaries safely.
Industrial networks choose the HDPE butt fusion end cap for permanent termination of abandoned branches.
