Note: Rubber toric seals must be clean and dry at assembly. All surfaces that contact the toric seals must be clean and dry at assembly. At assembly, apply a thin film of oil to the contacting surfaces of the metal seal. Seal rings must be assembled squarely with the bore. The toric ring must not bulge and the toric ring must not be twisted.
