Acetal Stem to Hose Barb Fitting
The John Guest acetal stem to hose barb fitting bridges quick-connect tube connections to traditional hose barb interfaces with a grip-then-seal collet design manufactured in the UK. Built from acetal copolymer with food-grade nitrile O-rings, this fitting handles potable water, beverages, CO2, compressed air, and vacuum applications with superior heat and chemical resistance compared to polypropylene alternatives.
| Material | Acetal copolymer body with food-grade nitrile O-ring |
| Connection Type | Push-to-connect stem to hose barb |
| Collet Design | Grip-then-seal with quick release |
| Temperature Range | Enhanced heat resistance vs. polypropylene |
| Applications | Potable water, food/beverage, CO2, air, vacuum |
| Manufacture | Designed and assembled in the UK by John Guest Speedfit |
Push the fitting fully onto the tube until seated, then turn onto the threaded connection point. The collet grips the tube while the O-ring creates a positive seal. To disconnect, unlock the nut, push the collet toward the fitting body, and pull the tube free. No tools required for installation or removal.
Compatible with John Guest tubing systems, RO units, beverage dispensing equipment, water filtration manifolds, pneumatic lines, and CO2 distribution systems. Suitable for potable water per NSF standards, food-grade applications, compressed air, inert gases, and vacuum service. Acetal construction provides superior chemical resistance and dimensional stability compared to polypropylene fittings in high-temperature or solvent-exposure environments.
