The John Crane Type 21 is a widely standardized elastomer-bellows\/single-spring rotating seal design that uses a carbon-graphite primary sealing face against a ceramic mating ring (stationary seat), with NBR\/Buna-N elastomers and a stainless steel spring and metal parts — materials consistent with what is visible in the photos (black carbon face, stainless coil spring, metal retainer). The seal accommodates a shaft size of approximately 1.625 inches (1-5\/8 in), decoded from the part number suffix and confirmed by the Goulds label notation \"TYP21(1.62)\"; the Type 21 design is a proven workhorse for water, light chemicals, and general process fluids in ANSI\/end-suction centrifugal pumps. The seal label (ID-HSD38384-4) is John Crane's internal traceability\/lot code, and the item is unused in original Goulds OEM packaging.\u003c\/p\u003e\n\u003ch3
