Nitrous Express Steel Compression Sleeve for Tubing AN Fitting Washer / Nut

The Nitrous Express steel compression sleeve (also called a tube sleeve or B-nut sleeve) is made for AN-style tubing connections in nitrous oxide and fuel plumbing. The sleeve slides over the tubing and sits inside an AN B-nut. When the nut is tightened onto the mating fitting, the sleeve holds the tube in place and helps make a secure, leak-resistant joint.

Key Features:

• Steel construction for strength under the pressures of nitrous and fuel systems
• Works with AN B-nuts and AN-style fittings for custom plumbing runs
• Compression-style design allows tubing to be connected without flaring
• Available in multiple AN and tubing size options to suit different plumbing layouts
• Made by Nitrous Express, a Wichita Falls, Texas manufacturer of nitrous oxide systems since 1996

Use these sleeves when building or repairing nitrous distribution lines, solenoid connections, and similar tubing runs. Pair each sleeve with the matching AN B-nut and tubing for a clean, dependable installation.
