1/16” High Pressure PEEK Internal Nuts (10 Pack)

PEEK nuts are used in VICI polymeric valves with zero dead volume fittings. They can also be used as alternatives to standard stainless steel nuts when polymeric ferrules are used (up to approximately 175°C).

These fingertight nuts have a knurled surface designed to provide sufficient sealing force on the ferrule without a wrench. Made for use with 1/16” OD tubing, nuts are .88” long. 

Sold in packages of 10.

PEEK nuts are intended for use only with polymeric ferrules, which seal with lower force than their stainless steel counterparts. Overtightening can result in breakage.
