PEEK Internal Nuts for 1/16” Hex, 0.87” Long - High Pressure (10 Pack)

These nuts are used in VICI valves and fittings with 1/16” zero dead volume (ZDV) ports. They can also be used as an alternative to stainless steel nuts with polymeric ferrules (up to approximately 175°C). 

They are 0.87” long; also available in 0.45” and 0.62” lengths. A fingertight 1/16” version is available in 0.88” length.

Hex style nuts allow wrench tightening; however, since they are polymeric, they can break and are recommended for use only when space is limited and fingers won't fit.

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.
