Opti-Max Cartridge Check Valves are designed to offer maximum performance and ease of use. From the sharp, consistent threads on OPTI-MAX custom housings, to the exacting standards used to match ball/seat sets in OPTI-MAX cartridges, every aspect of design and manufacturing reflects an unavoidable fact: when it comes to reliable check valve operation, quality and precision make a big difference. OPTI-MAX check valves offer many advantages over OEM check valve systems, and are better designed, better made and more reliable than any other after-market check valve product. Additionally, OPTI-MAX Free-Turn housings can be removed with the tubing still attached, accelerating check valve maintenance while reducing fitting wear.
