The 12 mm John Guest adaptor range provides practical push fit options for connecting plastic tubing to BSP threaded fittings or through panel connections. These adaptors are widely used in caravan plumbing, marine water systems, beverage equipment, irrigation layouts, and light commercial setups where a secure transition between push fit and threaded components is required.
Each adaptor features a reliable push fit connection on one end and either male BSP, female BSP, or bulkhead threading on the other. This design supports quick installation without tools while maintaining a stable seal in low pressure water and beverage systems.
Adaptors are manufactured from durable acetal or brass for strength, chemical resistance, and suitability for potable water applications.
John Guest fittings are known for consistent sealing and reliable push fit performance across caravan, marine, beverage, and commercial water systems. Hose Suppliers Australia supplies a complete selection of 12 mm adaptors with local stock in Brisbane and the Gold Coast and delivery available across Australia.
