Ideal for caravan plumbing fittings and RV upgrades, 15 mm John Guest adaptors provide practical push fit connections where plastic tubing needs to join BSP threaded parts or pass through panels. Installers gain reliable push fit convenience while keeping compatibility with male BSP, female BSP, and bulkhead threads.
Adaptors suit potable water layouts, marine plumbing, beverage lines, and general industrial systems that require a secure transition between push fit and threaded components. Materials in acetal or brass support long term performance in fixed and mobile installations.
John Guest fittings provide dependable sealing, repeatable installation, and consistent push fit performance across a wide range of water and air systems. Hose Suppliers Australia supplies an extensive range of 15 mm adaptors with local stock in Brisbane and the Gold Coast and delivery available across Australia.
