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. 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.
