Product questions
What material and coating does the Grayloc 51231N seal ring use?
The 51231N is listed as a size 5 seal ring in AISI 630 (17-4 PH) stainless steel with a green PTFE coating. It is a metal seal ring, not a solid PTFE ring.
What are the listed dimensions of the Grayloc 51231N?
The published drawing dimensions are A 0.625 in, C 1.094 in, D 0.375 in, E 0.125 in and F 0.125 in. These are drawing labels, not all bore or outside diameters; confirm the drawing and mating connector before ordering.
How do I check whether the 51231N fits my connector?
The ring is designated size 5, but that is a seal-ring designation, not a confirmed pipe size or equipment fit. Provide the connector and hub markings, equipment model and serial number if available, and service conditions for verification before ordering.
What temperature range is listed for the 51231N seal ring?
The published application range is -452 to +450 °F. This does not establish suitability for every service: confirm the fluid, pressure, temperature and complete connector requirements before use.
