Sea Tech 35 Series products are designed and manufactured to be trouble free for many years of service life. 35 Series products are designed and manufactured in Polysulfone, a high performance thermal plastic material. The majority of 35 Series products are approved and certified to NSF-61, NSF-14, CSA B137.5, ASTM F877, and IAPMO ASSE 1061-2006 and to the Uniform Plumbing Code (U.P. Code). 35 Series products are available in standard imperial inch sizes and interconnect with all Sea Tech 24 Series fittings. The Sea Tech quick connect design allows for quick and easy connections without installation tools. Simply cut the plastic, copper or CPVC piping and snap a Sea Tech fitting in place for a zero-leak connection.
