The Duotight elbow has a female 8mm fitting on one side and a male on the other. This fitting is designed for 8mm tubing like the 4mm x8mm EVABarrier OD Tubing. We also carry a version of this fitting for 6.3 ID X 9.5mm OD hose that is often used with gas. The male side will fit directly into another female Duotight fitting.

Duotight fittings feature a dual oring design that give  you a better, more reliable seal.

Keep the following in mind when using Duotight fittings:

  • You need to cut your hose straight (not at an angle) and firmly push the hose into the fitting until it locks in place.
  • If you need to remove the hose, but pull back on the collet. 
  • Can be used with liquid or gas. Made from acetal plastic and the orings are made from EPDM, which is chemical resistant.
  • Do not use with chlorinated cleaning solutions including bleach. This will degrade the plastic. 
  • No clamps are used. The hose is clamped internally by the collet and orings.
  • Temperature rated to boiling (212) and pressure rated to 150PSI.
