A damaged SCR cap can allow debris into the threaded connection, leading to loosening over time. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT21618. The cap serves as a protective cover for a threaded stud or fastener, securing the connection against contamination. Its plain mechanical function is to thread onto a 0.312-18 stud and provide a sealed closure. A concrete generic failure consequence is that a missing or cracked cap may permit moisture ingress, causing corrosion and eventual thread seizure. The listed spec is 18X1.000. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.03 POUNDS.

Part number variants: CT21618, ct21618
