Hose joiners are resistant to fuel, oil and glycol. These connectors are suited for use in vehicle fuel, heating and cooling systems. They are suited for continuous use between -40F and 284F (-40° and +140°C).

High quality rigid hose pipe connectors are made from Polyamide 6, 30% Glass Fiber Reinforced. 

Safe for long use between -40F and 284F (-40° and +140°C).

The connectors are resistant to a range of chemicals including hydrocarbon and mineral oils, all fuels and cooling system fluids as well as weak acids and alkalis.

5/32" (4mm) 4-4.5mm
3/16" (5mm) 5-5.5mm
1/4" (6mm) 6-7.5mm
5/16" (8mm) 8-9mm
3/8" (10mm) 10-11mm
1/2" (12mm) 11.5-13mm
