Duotight Inline Check Valve Push-In Fitting - 8mm (5/16")

Duotight Inline Check Valve for Reliable Gas Flow Control

Ensure one-way gas flow in your setup with the Duotight Inline Check Valve Push-In Fitting. Designed for 8mm (5/16") tubing, this fitting prevents liquid backflow into your gas lines, protecting regulators and manifolds from potential flooding. It activates with just 1 PSI of pressure, making it ideal for low-pressure applications.

Superior Seal and Durability

Featuring a dual O-ring design, Duotight fittings provide a secure, leak-proof seal that's more reliable than traditional options. Constructed from acetal plastic with EPDM O-rings, this check valve is chemical-resistant and suitable for both liquid and gas use, though we recommend it primarily for gas to avoid cleaning limitations.

Key Usage Tips for Optimal Performance

• Cut your hose straight and push firmly into the fitting for a secure lock.
• To remove, pull back on the collet for easy release.
• Avoid chlorinated cleaners like bleach to prevent plastic degradation.
• No clamps needed – the internal collet and O-rings provide a firm hold.
• Rated for temperatures up to 212°F and pressures up to 150 PSI.

Perfect for homebrewing, kegging, or any system requiring dependable one-way flow, this Duotight check valve combines ease of use with robust performance.
