Assembly into two-piece glands should not require any special fitting tools. This applies to both rod and piston seals. Fitting rod seals into one-piece glands should ideally use fitting tools. Sizes smaller than 0 30.00 should use light section seals. Standard section seals smaller than 0 30.00 and light section seals smaller 0 12.00 should be installed in open or split grooves only. Rod seals should be carefully deformed into a kidney shape and located into its groove. The seal should then be sized with a sizing tool. Fitting piston seals into a one-piece gland can be achived by hand. The PTFE component should be carefully stretched and positioned in its groove, prior to compressing to size by hand. For volume production, a pusher and sizing tool should be used. Full details of assembly tools can be obtained from Moontown.
