Made of plastic, these sleeves create a strong seal without damaging tubing.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Use these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on copper tubing.
