Ailbiuko 250-Pc Brass DOT Air Brake & Compression Fittings Kit — CA360 Brass, Tube Cutter Included

Ailbiuko 250-piece brass DOT air brake and compression fittings kit is a complete assortment of DOT push-to-connect, compression nylon, and brass pipe fittings for air systems and pipeline repairs. This all-in-one kit gathers the most commonly needed connectors, adapters and accessories for vehicle air brakes, pneumatic lines and general-purpose plumbing jobs. Built from CA360 brass and supplied with a tube cutter and Teflon tape, the set is designed to give technicians, fleet mechanics and DIYers the parts they need at hand—reducing downtime and multiple orders.

What sizes and fitting types are included in the kit?

The kit combines three families of fittings to cover both DOT push-to-connect and traditional compression and pipe-thread connections. Quantities are organized so you can complete repairs without hunting for single pieces.

• DOT push-to-connect: 38 pieces (straight male, 90° male elbow, 45° male elbow, union connector, union tee, Schrader valves)
• DOT compression nylon tube fittings: 157 pieces (various male/adapters, elbows, tees, plus 140 sleeve ferrules)
• Brass pipe fittings: 53 pieces (couplings, nipples, bushings, adapters, elbows, plugs and socket plugs)
• Accessories: 4 m Teflon tape and a compact tube cutter for on-site assembly

How durable and temperature-capable are these brass fittings?

All metal components are machined from CA360 brass, chosen for corrosion resistance and stable performance across a wide temperature band. The fittings meet DOT FMVSS 571.106 guidance for air-brake-compatible materials and are suited for typical vehicle and shop environments.

• Material: CA360 brass for wear and corrosion resistance
• Working pressure: vacuum to 300 PSI for airline applications
• Temperature range: -40°F to +250°F (follow tubing manufacturer limits)
• Pre-applied sealant on some threaded pieces plus included Teflon tape

How easy is installation and what tools are needed?

Installation is straightforward for anyone familiar with pneumatic or plumbing work; push-to-connect pieces fit quick-release style, while compression and pipe-thread parts require standard hand tools. The kit includes a tube cutter so you can size nylon tubing cleanly on the job.

• Push-to-connect joints insert and lock without extra tools
• Compression fittings need a wrench and proper ferrule seating
• Threaded parts may already have sealant; Teflon tape included as backup
• Tube cutter gives clean cuts to prevent leaks and premature wear

Which applications and systems benefit most from this set?

The assortment targets vehicle air brake maintenance but also supports shop pneumatic circuits and small-scale plumbing repairs. With a balance of push-fit convenience and threaded robustness, the set is useful for both emergency roadside fixes and planned shop overhauls.

• Heavy-duty and commercial vehicle air brake maintenance and patching
• Pneumatic tool lines, shop air feeds and compressor plumbing
• Small plumbing jobs requiring brass adapters and corrosion resistance
• Emergency spares kit for service vehicles and field technicians

Who is this for? This kit is designed for fleet mechanics, roadside service technicians, maintenance departments and hands-on DIYers who want a single, organized source of DOT-compliant fittings. If you frequently work on air brake systems, run pneumatic feeds in a shop, or need a robust parts set for field repairs, this 250-piece Ailbiuko assortment removes guesswork and keeps the right brass fittings within reach.
