4.11 Application of gland lubricant
To ensure proper installation, Endress+Hauser recommends using STL8 screw thread lubricant or equivalent on all
conduit screw thread and its taped opening.
STL8 Screw Thread Lubricant is a lithium based, anti-galling substance with excellent adhesion that maintains rain-
tightness and grounding continuity between conduit fittings. This lubricant has proven very effective between parts
made of dissimilar metals, and is stable in temperatures from –20 F to 300 F.
Do not use this lubricant on exposed current-carrying parts.
1. Holding the fitting piece at one end, generously apply the lubricant on the male threaded surface (at least five
threads wide) as shown below.
