duotight – 8mm (5/16”) Female x 8mm (5/16”) Female Double Tee Piece

duotight 8mm Push In Joiner (Double O-Ring)

This Tee Piece is suitable for our EVABarrier Beer & Gas hosing in 4mm ID & 5mm ID line or most lines with  8mm outer diameter.

It will not fit the 10mm OD EVABarrier line (with 6mm ID) but we do sell these larger 10mm duotight fittings separately.

duotight 1.10 Design Revision

No clamps 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, 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.
