John Guest - Acetal Reducing Union Quick Connect Fitting - Grey
Acetal Reducing Union Quick Connect Fitting
The John Guest acetal reducing union uses a precision grip-and-seal collet system for permanent or temporary connections on potable water lines, RO systems, beverage equipment, and pneumatic applications. Acetal copolymer construction offers superior strength and heat resistance compared to polypropylene, with food-grade nitrile O-rings for compliance with drinking water standards. Push to connect, twist to lock—no wrenches, no solvent, no leak risk.
Why installers choose John Guest fittings
Tool-Free Installation
Push the pipe fully into the collet, twist onto thread. No pipe dope, no Teflon tape, no torque wrench needed.
Grip & Seal Design
Collet teeth grip the tube while the nitrile O-ring seals against pressure. Removable by pushing collet and pulling pipe.
Food-Grade Materials
Acetal copolymer body with food-grade nitrile O-ring. NSF-compliant for potable water, beverage, and CO2 gas lines.
Heat & Strength
Acetal offers higher tensile strength and temperature tolerance than PP fittings, ideal for hot water and pressurized systems.
Multi-Application
Suitable for potable water, RO permeate and waste lines, pneumatic air, inert gases, vacuum, and CO2 beverage systems.
UK Manufacturing
Designed, manufactured, and assembled in the UK by John Guest Speedfit to ISO quality standards since 1961.
Where to use this fitting
The John Guest acetal reducing union is compatible with polyethylene, nylon, and reinforced PVC tubing in reducing configurations. Common applications include reverse osmosis feed and drain lines, under-sink water filter connections, inline sediment and carbon filter plumbing, refrigerator and ice maker supply lines, beverage dispensing systems, pneumatic control lines, and toilet and tap installations. Verify tube OD and thread size match your system requirements before ordering.
