System Engineering

Every fitting is built around a precision-engineered sealing system designed for strength, alignment, and long-term reliability.

01

Grip Ring

High-strength stainless steel grip ring locks onto the pipe securely to resist pullout under pressure.

02

Spacer

Engineered polymer spacer keeps internal components aligned and helps ensure correct pipe insertion depth.

03

O-Ring

Premium EPDM sealing ring creates a dependable seal, including on challenging pipe conditions, tested to a 120 bar spike pressure (8 bar continuous working pressure).

Every component is designed to work together as one complete plumbing system.

UNITWIST fittings do not require thread tape. Smart washers effectively create secure seals.
