The 16703335 from Oetiker is a set of 1/2” PEX stepless  stainless steel cinch clamps, specifically designed for use with a PEX clamp tool, PEX tubing, and crimp style PEX fittings. Ideal for installing radiant heating system in confined spaces. Use with fittings and tubing of appropriate sizes.  

The 16703335 is a stepless cinch clamp. The ear clamp’s special design eliminates steps and/or overlaps on the inner circumference of the clamp for a 360° leak-free seal. Because the tongue resides in a groove, the “tongue-in-groove” feature exerts pressure on the assembled parts over 360°, enabling the clamp to apply a continuous radial force completely around the connection’s diameter. 

These clamps can be easily installed using 3-Handle Ratchet Pincer Installation Tool for Oetiker PEX Clamps. Oetiker 3-Handle Ratchet Pincer Installation Tool, Item No. 14100280

Optional - Included With Clamp Pack
