Installation Procedure

Note: O-rings, gaskets and seals should always be replaced. A used O-ring may not have the same sealing properties as a new O-ring. A reconditioning procedure should not be degraded because of a low cost component such as an O-ring or a gasket. Use 1U-6396 O-Ring Assembly Compound during the assembly procedure.


Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.
