Install tips for reliable performance

1. Ensure both ends are clean and free from debris before installation.
2. Apply a light lubricating film of compatible hydraulic fluid to the O-rings to ease seating and reduce wear during assembly.
3. Thread by hand to avoid cross-threading, then snug with a proper wrench; never over-tighten to protect the O-rings and inlet/outlet seating.
4. Check for leaks after cycling the hydraulic system and tighten as needed following standard service procedures.
