This elbow piece is suitable for our EVABarrier Beer & Gas hosing size -  9.5mm (3/8") OD x 6.3mm (1/4") ID
 
duotight 1.10 Design Revision
 
No clamps are necessary!

We do recommend cutting your hosing straight, not on an angle, to ensure the line has a complete seal. To remove the fitting simply push in the collet and the hose can be removed. These push-in fittings are suitable to be used up to 100 psi
 
These push in fittings have been engineered for maximised performance in both gas and liquid applications. Compared to other push-in fittings on the market, duotight takes the double safety approach to all of the connections with two EPDM o-rings per hose port. No other push-ins on the market have EPDM o-rings, let alone two! per push-in connection.
 
What is EPDM?
EPDM = Ethylene Propylene Rubber which has excellent chemical resistance including being compatible with ozone, oils, a wide variety of alkaline and acid compounds, water, alcohol, ketone, and beverages.
 
EPDM is also resistant to aging, weather and will not perish easily like other rubber compounds.   When compared with silicon and vinyl EPDM has better gas transmission rates, better wear resistance, is BPA free, and is the number one choice for many long-lasting food-grade applications.
