AquaLock: Professional-Grade Push-to-Connect Fittings

AquaLock, manufactured by Watts, represents a leading solution in push-to-connect fitting technology for marine, RV, and plumbing applications. Designed and manufactured for many years of service life, these fittings have earned their reputation as a trusted choice among boat builders, marine distributors, and professional installers worldwide.

Tool-Free Installation Technology

What sets AquaLock fittings apart is their innovative push-to-connect design that eliminates the need for specialized tools or soldering equipment. AquaLock features a stainless steel gripper ring that is resistant to corrosion and interlocks with multiple materials without any tools, making installation fast and accessible even in tight spaces. Installation is fast and easy on almost any CTS-sized pipe—reducing the risk of installation errors and leaks. This design philosophy means fewer callbacks for installers and more reliable connections for end users.

Versatile Material Compatibility

AquaLock fittings are engineered to work seamlessly with a wide range of pipe materials including PEX, copper, and CPVC. This versatility makes them ideal for retrofitting older systems or building new installations where different pipe materials may need to connect. The fittings are constructed from high-performance materials including polysulfone thermoplastic and lead-free brass options, ensuring both durability and compliance with modern potable water standards.

Marine and RV Applications

The number one choice for boat builders and marine distributors worldwide, AquaLock fittings excel in demanding marine environments. They are fit for many applications including potable water, raw and fresh water washdown, live well systems, hot and cold water lines, drain lines, and windshield washing systems. The corrosion-resistant construction stands up to saltwater exposure and the vibration common in marine and recreational vehicle applications.

Product Range and Formats

AquaLock fittings are offered in several diameters in both Inch (Imperial) and Metric formats, providing flexibility for domestic and international applications. The product line includes elbows, tees, couplings, valves, adapters, manifolds, and specialized hose assemblies. Both plastic and brass fitting options are available depending on application requirements and pressure ratings.

Reliability Under Pressure

AquaLock fittings are engineered to withstand demanding operating conditions. Many models are rated for working pressures up to 250 PSI and are certified to rigorous industry standards including NSF-61, NSF-14, and IAPMO specifications. The EPDM o-ring seals provide leak-free performance across a wide temperature range, while the stainless steel gripping mechanism ensures connections remain secure even under vibration and thermal cycling.
