Quality Warranty For 50 Years

Twistloc products undergo long-term test programmes and strict quality standards. When correctly installed using Twistloc pipe, we offer a 50 year warranty against the defects in materials and manufacturing across our standard Twistloc Fittings range from the date of delivery.

(This 50-year guarantee does not cover the mechanical components within our range of valves and threaded adaptors. Sealing washers for both the valves and adaptors are also not covered within the 50- year guarantee. For the above-mentioned product types, these will hold a 2-year guarantee for manufacturing defects from the date of original purchase at no additional cost.)
