Sea Tech Pressurized Water System Tubing & Fittings
Sea Tech Quick-Connect Fittings for Marine Pressurized Water Systems
When it comes to reliable, leak-free plumbing aboard a boat or RV, few names carry as much weight as Sea Tech. A subsidiary of Watts Water Technologies, Sea Tech has spent decades engineering push-to-connect fluid connection solutions purpose-built for the demands of the marine environment. Their pressurized water system tubing and fittings represent one of the most innovative approaches to onboard plumbing available today — combining ease of installation with proven, certified performance.
What Sets Sea Tech Apart in Marine Water Fittings
The defining characteristic of Sea Tech's pressurized water system fittings is their patented quick-connect design. Unlike traditional barbed or threaded fittings that require tools, clamps, or crimping equipment, Sea Tech's push-to-connect system lets installers simply press a fitting onto the tubing for an immediate, secure seal. This push-to-connect design allows DIY boaters and professionals alike to create secure, leak-proof connections simply by pressing the fitting onto the tubing, eliminating the need for specialized crimping or soldering tools.
A key engineering advantage is how Sea Tech connectors engage the tubing. Sea Tech connectors snap on the outside of the tubing, eliminating the need for an inner barb — a design that not only speeds up installation but also maximizes water flow through the line. Tees and elbows in the system can rotate to create a custom manifold configuration, giving builders and DIYers the flexibility to route lines around the unique geometry of any vessel.
Product Series and Compatibility
Sea Tech offers fittings across several distinct series, including the widely used 35 Series and 45 Series, along with metric options in the 15 mm and 22 mm Series. The 35 Series products are manufactured in Polysulfone, a high-performance thermoplastic, and carry certifications to NSF-61, NSF-14, CSA B137.5, and ASTM F877. Fittings are available in both standard inch and metric sizes, serving a global base of boat builders and marine distributors.
Tubing compatibility is another strength. Sea Tech fittings are designed for use with PEX tubing, copper, CPVC, and various polyethylene tubings including LDPE, MDPE, and HDPE — making them an excellent choice for diverse onboard water systems. This material versatility makes it straightforward to retrofit an older vessel or spec a new build without committing to a single pipe material throughout.
Applications Across the Boat
Sea Tech pressurized water system components are suitable for a wide range of onboard applications, including potable water, raw and fresh water washdown, live well systems, hot and cold water lines, drain lines, and windshield washing systems. The fittings are designed to be rust-proof and corrosion-resistant, typically constructed from marine-grade polymers and stainless steel components — critical qualities in the saltwater environment.
All Sea Tech fittings and valves are certified to ANSI, NSF, and ASTM standards, and the brand meets or exceeds all ABYC (American Boat and Yacht Council) and RVIA standards. Sea Tech is also a member of the Water Quality Association (WQA), underlining the company's commitment to safe, potable-water-grade performance.
Whether you're a professional boat builder or a weekend warrior tackling a DIY plumbing refit, Sea Tech's pressurized water system tubing and fittings deliver the kind of confidence that comes from decades of marine-focused engineering.
