Duotight – 9.5mm (3/8”) OD Plastic Retaining Circlip

Ensure a secure, leak-free connection in your brewing and beverage systems with this 9.5mm (3/8″) OD Duotight retaining circlip. Made from high-quality, food-grade plastic, it firmly locks push-in fittings in place, preventing accidental line disconnection — especially under pressure.

Ideal for use in homebrew setups, kegging systems, glycol chillers, fermentation cooling coils, and beer dispense lines, this circlip is essential for maintaining consistent pressure in your draft system. Commonly used with Duotight fittings in kegerators, keezer builds, and mobile dispense setups, it keeps gas and liquid lines locked tight, even during movement or vibration.

Compatible with Duotight and KegLand fittings, including the TempTwister system, it’s a small but critical part of any high-quality dispense or cooling configuration.
