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.
