Ailbiuko DOT Air Brake Fittings Kit — 200 Pc Brass & Nylon Assortment with Tube Cutter and PTFE Tape

Ailbiuko 200 Pcs Brass DOT Air Brake Line & Compression Fittings Kit is a comprehensive set of DOT push-to-connect, compression nylon, and brass pipe fittings plus tools suited for air brake and pneumatic line maintenance.

This all-in-one assortment groups the most commonly used fittings and small tools so technicians, hobbyists, and fleet maintenance teams can make fast, durable air-line repairs and installations without hunting for individual parts. Each component is manufactured from CA360 brass or compatible nylon parts and supplied with a roll of PTFE thread tape and a tube cutter to help secure threaded connections and cut tubing to length.

What types of fittings are included and why do they matter?

The kit separates three fitting styles to cover push-to-connect DOT lines, compression-style nylon tubing, and standard brass pipe threads. That variety lets you match the connection method to the system you’re servicing—whether quick-connect repairs, compression seals, or threaded pipe joints.

• DOT push-to-connect: straight, 90° elbow, union, tee, 45° elbow, schrader valves (30 pcs)
• DOT compression nylon fittings: straight, 90° elbow, union, tee, 45° elbow plus 95 sleeve ferrules (123 pcs)
• Brass pipe fittings: couplings, nipples, bushings, adapters, street elbows, plugs, socket plugs (45 pcs)

How durable are these fittings and what operating range should I expect?

Fittings are made from CA360 brass and designed to meet DOT FMVSS 571.106 guidelines for air brake components. They resist corrosion, tolerate a broad temperature window, and maintain sealing under typical pneumatic pressures.

• Working pressure: vacuum to 300 PSI (follow tubing maker limits)
• Temperature range: −40°F to +250°F
• Material: CA360 brass for metal parts, engineered nylon for compression tubing components

How easy is installation and what tools are provided?

The kit is designed for field use: push-to-connect pieces install quickly while compression and threaded parts require simple hand tools. Several threaded pieces ship with pre-applied sealant and a roll of Teflon tape is included for additional leak protection.

• Push-to-connect fittings engage tubing without ferrules for fast service
• Compression fittings use included ferrules for a tight seal when tightened
• Threaded fittings accept PTFE tape or pre-applied sealant for leak resistance
• Tube cutter included for clean, square tube ends

What comes in the box and how does the assortment help on real jobs?

The kit items are counted to give you a ready stock of common repair parts so you can replace a damaged fitting, reroute tubing, or build a small manifold without ordering extras. The mix reduces downtime by providing the right connector for many system layouts and materials.

• Total count: 200 pieces plus 4 m PTFE tape and a tube cutter
• Convenient counts of elbows, unions, tees, adapters, plugs and ferrules for repeated repairs
• Useful for roadside, shop, or DIY pneumatic projects

Who is this for: technicians, truck and trailer maintenance crews, light fabrication shops, and DIYers who work with air brake lines or pneumatic tubing will value the breadth of connector types and included tools. If you need a versatile, on-hand supply of DOT-compatible fittings and brass pipe connectors to address leaks, reroutes, or new installations, this kit provides a practical, ready-packed solution.
