Previous Solution: Failing Cylinder Seal

摘要

The seal house gave us the information below on limits of extrusion gaps, durometer info and back-ups. While the seal material being supplied had a 5,000 PSI rating with a .014" gap, the cylinder end cap did not seem to stretch that much while we were there. Some suggested that possibly the grade 8 cap screws were not to spec or of a lesser grade. First, all steel Allen head cap screws are grade 8, so we felt the correct cap screws were being used. However, the mechanic said they did seem tight (binding) when he felt they should have been loose.
