Installation Notes

This washer is installed by mechanics, HVAC technicians, electricians, and plumbers as part of standard fastening procedures. Always power down or depressurize the relevant system before disassembling any fastened joint. Use the appropriate driver or wrench for the mating fastener and avoid overtightening, which can deform the washer and reduce its load-distributing function. Verify dimensional fit with the fastener and mating surface before installation.
