Ailbiuko 250-Pc Brass DOT Air Brake & Compression Fittings Kit — CA360 Brass, Includes Teflon Tape & Cutter

The Ailbiuko 250-piece brass DOT air brake and compression fittings kit is a full-service collection of DOT push-to-connect, compression nylon, and threaded brass pipe fittings designed for maintenance and repairs on air brake lines and pneumatic plumbing.

This all-in-one kit groups DOT-approved brass connectors, a broad range of compression nylon fittings, assorted threaded brass pipe pieces, a roll of Teflon tape and a tube cutter into a single organized box. Components are manufactured from CA360 brass to meet D.O.T. FMVSS 571.106 guidance for air-brake hardware, offering corrosion resistance and a wide operating temperature range. Whether you are replacing worn connectors, building custom airline runs, or carrying a comprehensive roadside repair set, the Ailbiuko kit aims to reduce trips to the hardware store by providing common sizes and styles in one package.

What types of fittings are included and why does that matter?

The kit contains three distinct categories so you can handle push-to-connect installations, nylon tubing compression hookups, and threaded pipe connections without needing separate packs. This diversity allows compatibility across vehicle air systems and general pneumatic plumbing jobs.

• DOT push-to-connect fittings: 38 pieces including straight, 90° and 45° male connectors, unions, tees, and schrader valves.
• DOT compression nylon tube fittings: 157 pieces including male connectors, elbows, unions, tees, plus 140 sleeve ferrules.
• Brass pipe fittings: 53 pieces covering couplings, nipples, bushings, adapters, elbows, plugs and socket plugs.
• Accessories: 4 m Teflon tape and a compact tube cutter for on-the-job sealing and sizing.

How durable and safe are the fittings for air brake systems?

Fittings are machined from CA360 brass and are engineered to meet D.O.T. guidance for air-brake components, offering solid corrosion resistance and thermal tolerance. They are intended for routine maintenance and repair where DOT-compatible materials are required, but always follow vehicle manufacturers’ tubing and installation recommendations.

• Material: CA360 brass for long-term corrosion resistance.
• Pressure: usable up to 300 PSI working pressure from vacuum to max under recommended conditions.
• Temperature tolerance: rated approximately -40°F to +250°F; check tubing maker limits.
• Pre-sealed threads: some threaded parts include pre-applied sealant; extra Teflon tape provided.

How easy is installation and what tools will I need?

The push-to-connect pieces install quickly—simply push tubing into the fitting until seated—while compression and threaded pieces require basic hand tools for a secure joint. The included tube cutter helps size nylon tubing cleanly; for threaded fittings, use appropriate wrenches and the supplied Teflon tape or thread sealant as needed.

• Push-to-connect: tool-free seating for nylon airline tubing.
• Compression fittings: require tightening with appropriate wrenches until ferrules compress.
• Threaded brass fittings: use wrench and thread tape/sealant for leak-free joints.
• Kit convenience: includes ferrules and a tube cutter to speed installations.

Which maintenance and repair tasks will this kit cover?

It covers most common air-line tasks: replacing damaged connectors, building short runs, installing valves, or converting between tubing and threaded systems. The variety of elbows, unions and adapters helps adapt fittings to tight spaces and non-standard layouts.

• On-vehicle air brake repairs and spare-parts replacement.
• Workshop pneumatic line assembly and rapid prototyping.
• Conversions between nylon tubing and threaded pipe systems.
• Emergency roadside fixes with compact, organized parts.

Who is this for? The Ailbiuko 250-piece kit is intended for fleet maintenance techs, independent mechanics, DIYers who work on trucks or trailers, and anyone who needs a broad selection of DOT-style brass and compression fittings on hand. It’s useful for preventative maintenance, emergency repairs, and shop projects where compatibility across tubing and threaded systems saves time and trips to the supply store. Always pair fittings with compatible tubing and follow the vehicle or equipment maker’s specifications for pressure and temperature limits.
