got a groove set up for a 1 inch quad ring, is this the one thats 1 x 3/32?
Answer by: Customer Support on Dec 6, 2025, 8:12 PM
The key dimensions given are a 1 inch outer diameter and a 3/32 inch thickness. If your groove is sized for that 1 inch OD quad ring with a 3/32 cross section, this matches those dimensions.

part number QR-4120, is that the same as C1FC87 or MI-01234942? got a few different numbers floating around on my paperwork and want to make sure im ordering the right seal
Answer by: Customer Support on Jan 19, 2026, 3:11 PM
All three of those numbers refer to the same part. QR-4120 is the primary SKU, and C1FC87, MI-01234942, and MINO-00407X70524 are all recognized alternate part numbers for this quad ring. If any of those showed up on old invoices or equipment documentation, you're looking at the right seal.
