COMPATIBILITY
Ideal Applications
The John Guest Acetal Union Connector is designed for connecting tubing to threaded ports on taps, toilets, water filters, reverse osmosis systems, beverage dispensers, and pneumatic equipment. The acetal construction offers greater strength and heat resistance than standard polypropylene fittings, making it suitable for installations where durability and temperature tolerance are required. Compatible with John Guest push-fit tubing in corresponding sizes.
🔧 Pro tip: Before connecting, inspect the collet and O-ring for any debris or damage. A clean insertion ensures the grip-and-seal mechanism engages properly and prevents leaks under pressure.
