TRO Rod T Piston Seals

The Rod T-piston seal is designed for installation in standard commercial O-ring grooves. Designs should allow for proper lead-in angle (identical to those specified for O-rings). Due attention should also be given the chamfering and/or recessing of shoulders, ports and threads, which may damage the seal in installation or operation.
