Sealing Locknuts "Blue-Lok"®

Leak Proof Sealing Locknuts

Designed for applications that need to be sealed against water, oils, and other liquids, our premium sealing locknuts primarily cater to the hydraulic and pump industries. We custom produce our sealing locknuts to meet precise customer specifications. Our sealing locknuts include thread sizes between .25 of an inch and 1.500 inches in diameter.

This unique one piece design, which includes a molded circular polymer insert, replaces the need for o-rings and support washers to provide sealing. We can accommodate needs for custom nylon and PTFE applications withstanding temperatures up to 300 degrees Fahrenheit. Additionally, our locknuts seal at pressures up to 10,000 PSI.

For over a century, Industrial Nut Corp. has established itself as a leader in the manufacturing of premium special nuts and other special machined parts. This same dedication to quality helps to ensure that all our sealing locknuts meet high customer standards and expectations. Contact Industrial Nut Corp. today to learn more about our products.
