This Duotight Push-Fit Elbow - 8mm x 8mm - will allow you to join beer or gas line sections on your kegging system. Simple to use and requires no tools. Duotight 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. These push in fittings are suitable to be used up to 100 psi. They are extremely easy to use and allow you to simply push your beer and gas line straight into these fittings. No need to purchase clamps. To remove the fitting simply push in the collet and the hose can be removed. We do recommend cutting your hosing straight, not on an angle, to ensure the line has a complete seal.
