ABSTRACT:
A spring loaded seal is placed between three continuous groove walls between mating parts adjacent to a pressure transmitter isolator. The seal includes a resin ring with two ring walls conformable to two of the groove walls. A third ring wall has a continuous slot extending into the ring. A coil spring is placed in the slot such that, upon mating of the parts, the third wall presses the coil spring toward the slot. This compresses the coil spring to sealingly force the first and second outer ring walls against the first and second groove walls respectively with a controlled force. The coil spring's compression controls the sealing force to limit undesired distortion of the groove walls.
