Duotight are the push in fitting with superior sealing capacity due to the double o-ring sealing design. The secret to the superior sealing performance is not just using high quality EPDM o-rings but also use two of them. The double o-ring means literally twice the sealing surface making duotight fittings even more reliable reducing the chance of a leak significantly.
The double o-ring system also means the user can bend the hose with much tighter radius without causing leaking issues. This typically can be an issue with other fittings. This combination of factors makes duotight fittings the most reliable push fit fittings on the market.
No clamps necessary!
It is recommended to cut hose 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. Duotight takes the double safety approach to all of the connections with two EPDM o-rings per hose port.
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.
