Speedfit Double Check Valves
Speedfit fittings have been designed for use with both plastic and copper pipe, in diameters of 10mm to 28mm, and are approved by the Water Research Centre within the requirements of the UK Water Fittings Byelaws Scheme.
The twist and lock Speedfit fittings have a collet with stainless steel teeth and 'O' ring to provide a permanent leak-proof seal. A simple twist of a screw cap locks the pipe into position and increases the compression of the 'O' ring seal to give added security.
Speedfit products are fully certified by the British Board of Agreement, approved by the Water Regulations Advisory Scheme, and are kitemarked to BS7291, Parts 1 and 3.
Speedfit products are compatible with:
- Mains fed and indirect cold water systems
- Vented and unvented hot water systems
- Vented central heated systems
- Sealed central heated providing temperatures and pressures comply with BS7291 Parts 1 and 3 Class S
Please note: Speedfit should NOT be used for gas, fuel oil or compressed air applications.
