The Plasson Compression Fit Coupler is designed for connecting water mains pipes and various water supply pipes across infrastructure, agriculture, and horticulture sectors.

Crafted from virgin Polypropylene, this fitting offers exceptional impact strength and stress resistance, making it incredibly robust and suitable for outdoor environments, including direct sunlight and frost conditions. The coupler features a captive O-ring to ensure a watertight seal, facilitating easy and rapid installation through simple tightening. It is tested to withstand working pressures of up to 16 bar and boasts a 50-year design life, with WRAS approval. The captive 'O' Ring seal provides lifetime protection against leaks, and its impressive stress resistance ensures easy installation and a leak-free seal.
