Ailbiuko 200-Piece Brass DOT Air Brake & Compression Fittings Kit — CA360 Brass, Push-to-Connect + Tools

The Ailbiuko 200-piece brass DOT air brake and compression fittings kit is a complete, vehicle-ready assortment of DOT push-to-connect, nylon compression, and brass pipe fittings for installing and repairing air brake and pneumatic lines.

Whether you’re servicing heavy trucks, trailers, RV air systems, or workshop pneumatic lines, this kit brings a broad selection of DOT-compliant brass parts and essential accessories in one compact package. The set combines CA360 brass components, a range of connector types and sizes, and a few hand tools to help you make secure, low-permeability connections that withstand road vibration and temperature swings.

What exactly is included in the 200-piece kit?

The kit is divided across three fitting families plus accessories to cover most common air brake and pipe repair scenarios. Counts and types are provided so you can inventory before beginning a job.

• 30 DOT push-to-connect fittings: straight male, 90° male elbow, union connectors, tees, 45° elbows, and Schrader valves.
• 123 DOT compression nylon tube fittings: straight male, 90° male elbow, unions, tees, 45° elbows, and 95 sleeve ferrules.
• 45 brass pipe fittings: hex couplings, nipples, bushings, extension adapters, 90° street elbows, hex plugs and socket plugs.
• Plus a 4 m roll of Teflon tape and a small tube cutter for on-the-job sealing and cutting.

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

Components are machined from CA360 brass designed for strength and corrosion resistance in pneumatic environments. The fittings meet DOT FMVSS 571.106 air brake system requirements and are intended for use within the stated pressure and temperature ranges.

• Material: CA360 brass for corrosion resistance and dimensional stability.
• Pressure capability: rated for vacuum up to 300 PSI where applicable.
• Temperature range: -40°F to +250°F (follow tubing maker limits for exact system ratings).
• Low permeability and vibration resistance suitable for vehicle applications.

How straightforward is installation for a DIY mechanic?

Many parts are push-to-connect for fast assembly; compression fittings and threaded pipe parts require basic hand tools. The kit includes Teflon tape and a cutter, and several threaded pieces arrive with pre-applied sealant to reduce assembly steps.

• Push-fit pieces insert quickly and secure without soldering.
• Compression fittings require ferrule placement and tightening with wrenches.
• Threaded pipe fittings accept Teflon tape or pre-applied sealant for leak prevention.
• Compact tube cutter helps produce clean tubing ends for reliable seals.

Which applications and vehicles are these fittings best suited for?

The assortment targets heavy-duty and light-duty pneumatic systems: commercial trucks, trailers, RV braking and leveling lines, and shop compressed-air plumbing. It’s also useful for emergency roadside repairs where a range of connector types is needed quickly.

• Truck and trailer air brake repairs and replacements.
• RV and motorhome pneumatic systems and waterless brake lines.
• Workshop compressor lines, air tools, and small pneumatic circuits.
• On-the-road emergency fixes and preventive maintenance kits.

Who is this for: Ailbiuko’s 200-piece kit is designed for fleet technicians, mobile mechanics, RV owners, and dedicated DIYers who need a wide selection of DOT-compliant brass and compression fittings on hand. If you require a versatile assortment for routine maintenance, emergency repairs, or building pneumatic runs, this kit consolidates common connectors, ferrules, and pipe adaptors into one organized set.
