What is an Aqualock coupling?
A mechanical pipe coupling joins or repairs plain-ended pipes without welding or threading. Rubber seals grip the pipe as bolts or end nuts are tightened.
Couplings are quick to fit, even in wet trenches. Therefore, water utilities and plumbers use them for repairs, extensions and joining different pipe materials.
