Duotight Push-In Fitting - 9.5 mm (3/8 in.) x 1/2 in. BSP

This Duotight fitting with 1/2" male thread is perfect for attaching to the Copper Counterflow Chiller and using with 1/2" female threaded Camlock and QD fittings. Compatible with EVABarrier 9.5 mm OD tubing.   Duotight fittings are high-quality push-in fittings that seal tight and offer superior sealing capacity due to the double O-ring sealing design.   High-Performance Double O-Ring Design: The secret to Duotight’s superior sealing performance comes from the fact that they use not one, but two high-quality EPDM O-rings.  The double O-ring means they have literally twice the sealing surface when compared with other push-in fittings.  This makes them more reliable and significantly reduces the chance of leakage.   The double O-ring system also means that tubing can be bent at a much tighter radius without causing leaking issues, which can be an issue with other fittings.  This combination of factors makes Duotight the most reliable push-in fittings on the market.
