duotight - 9.5mm (3/8") One Way Check Valve (Gas)

Looking for high quaility push in fittings that will seal tight?  Duotight are the push in fitting with superior sealing capacity due to the double o-ring sealing design.

Why do we use Double O-rings?
The secret to our superior sealing performance is not just the fact that we use high quality EPDM o-rings but also use two of them.  The double o-ring means we literally have twice the sealing surface surface when compared with other push in fittings.  This makes our fittings even more reliable and reduces the chance of a leak significantly.

The double o-ring system also means that we can bend the hose with much tighter radius without causing leaking issues.  This typically can be an issue with other push in fittings.  This combination of factors makes duotight fittings the most reliable push fit fittings on the market.
