Wide Selection Of Male Straight Unions (Crimp)

Wet underfloor heating systems circulate water at pressure, so secure pipe fittings are vital. Underfloor heating leaks can be hard to find and access after installation, causing damage before they’re identified. This makes crimp fittings, like male straight unions, ideal. Thousands of pounds of pressure are used to deform the fitting and compress sealant against the inner tubing, ensuring a watertight connection.


WRAS-Approved Male Straight Unions (Crimp)

Our WRAS-approved male straight union fittings are made from high-quality nickel-plated brass with a stainless-steel sleeve and a secure double ‘o’ ring seal, ensuring connections are leakproof. They’re suitable for use in potable water supply, central heating and underfloor heating systems, and come in ½” and ¾” sizes to suit your requirements. We also offer a range of equal straight union, male unequal union and demountable female straight union crimp fittings.
