Sea Tech: Trusted Push-to-Connect Plumbing Solutions for Marine, RV, and Home

Sea Tech, Inc. has been a cornerstone of reliable fluid connection technology since 1995, building a reputation as a go-to source for boat builders, RV manufacturers, and plumbing professionals alike. Now operating under the AquaLock™ brand — a division of Watts Water Technologies — Sea Tech's product legacy lives on through an expansive lineup of quick-connect fittings, valves, manifolds, and tubing engineered for demanding real-world applications.

What set Sea Tech apart from the very beginning was a commitment to tool-free, leak-free installation. Their push-to-connect design eliminates the need for compression sleeves, crimping tools, adhesives, clamps, or welding. A simple push seats the tubing securely, while stainless steel gripping teeth in the collet create a zero-leak connection that can also rotate under pressure — a critical feature in vibrating or dynamic environments like boats and RVs.

Sea Tech pipe fittings are compatible with virtually every major tubing material on the market, including PEX, copper, CPVC, LDPE, MDPE, HDPE, and polypropylene. This broad material compatibility makes them equally at home in a boat's freshwater system, an RV galley line, or a residential water filtration installation. Fittings are available in both standard inch (CTS) and metric sizes, giving OEMs and aftermarket installers the flexibility to spec exactly what they need.

For onboard water systems and pressurized plumbing runs, Sea Tech's pressurized water system tubing and fittings are designed to handle hot and cold water lines, potable water distribution, raw and fresh water washdown, live well systems, and even windshield washing circuits — all certified to ANSI, NSF, and ASTM standards and meeting ABYC and RVIA requirements.

Beyond connectors, Sea Tech offers a full suite of plumbing parts and accessories that round out any installation, from manifolds and tubing cutters to clips and locking accessories for added connection security. Their nylon pipe and hose fittings provide a lightweight yet durable option for applications where corrosion resistance and cost efficiency are priorities. And for flow control, Sea Tech ball valves deliver dependable shut-off performance in compact, marine-grade form factors.

Whether you're a professional boat builder, a weekend DIY boater, or a plumber working on a residential water treatment system, Sea Tech's AquaLock technology offers a proven, code-compliant solution that reduces installation time and callback risk. It's the kind of engineered simplicity that earns a brand its long-standing trust in demanding industries.
