Be sure to clean and Inspect sealing surfaces. Scratches / roughness cause leaks and seal wear.
Unevenness causes seal extru- sion. If defects cannot be pol- ished out, replace the compo- nent.
Be sure to use only specified O-rings. Inspect O-rings for any damage. Take care not to file O-ring surfaces. When installing an O-ring into a groove, use grease to hold it in place.
While lightly tightening split flange halves, check that split is centered and perpendicular to the port. Hand-tighten bolts to hold parts in place. Take care not to pinch the O-ring.
Tighten bolts alternately and di- agonally, as shown, to ensure even tightening.
Do not use air wrenches. Using an air wrench often causes tight- ening of one bolt fully before tightening of the others, resulting in damage to O-rings or uneven tightening of bolts.
