The Seal Sizer supports the correct sizing of seal sets after placement on a piston assembly. Inner and outer seal portions are first guided onto a mandrel and pressed onto the piston using a ring pusher. Once both seal portions are seated, the piston assembly is guided into the seal sizer opening.Attributes:• Reduces risk of seal distortion during piston insertion.• Supports smooth piston entry into mating assemblies.• Prevents uneven seal contact that may lead to leakage.Applications: The Seal Sizer is used during the installation of piston seals. It surrounds the piston assembly to compress the seals evenly, ensuring proper sizing before final insertion into operating assemblies.
