Duotight Push-In Fitting - 8 mm (5/16 in.) Elbow

(1 review) Write a Review

This Duotight elbow is for 4mm ID X 8mm OD EVABarrier hose/tubing. This size is normally used for liquid, but is used for gas on Duotight inline regulators and some other Duotight products.

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.

    I love duotight fittings. easy to use in just about any configuration. Need to reconfigure? No problem, take it apart and start again.
