TRUCFUSION AC Fitting Set — 42-Piece #6 #8 #10 Kit with R134a Valves and O-rings

TRUCFUSION Air Conditioning AC Fitting Set is a 42-piece kit of #6, #8, and #10 fittings (straight, 90°, 45°) plus R134a valve fittings, O-rings and clamps for reliable HVAC hose connections.

This comprehensive AC fitting kit groups the common thread sizes and angles technicians and DIYers need to service automotive and light-commercial air conditioning systems. Built from an aluminum tube body paired with zinc-plated iron components, the set balances strength and corrosion resistance. The included O-rings use a beadlock-style seating to reduce leaks and make repeated installations simpler, while R134a-ready valve fittings let you work with refrigerant-equipped systems without sourcing extra parts.

What exactly is included in the 42-piece TRUCFUSION kit?

The kit is organized to cover typical hose sizes and fitting angles for AC service. You get multiple straight and angled fittings, dedicated valve fittings for R134a systems, replacement O-rings and clamps to finish installations.

• 18 AC fittings across #6, #8, #10 in 180° (straight), 90° and 45° orientations.
• 4 AC fittings with built-in R134a pressure valves for #8 and #10 sizes (180°, 90°).
• 18 O-rings sized for #6, #8, #10 fittings and 2 hose clamps for securing connections.
• Thread sizes: 5/8-18UNF, 3/4-16UNF, 7/8-14UNF to match standard HVAC hoses.

How does the material choice affect durability and corrosion resistance?

Combining an aluminum tube with zinc-plated iron components gives the fittings a robust core and a plated finish that resists rust in humid or salty environments. The materials are selected to stand up to vibration and repeated assembly without deforming threads or seating surfaces.

• Aluminum tubing for lighter weight and reduced galvanic issues with copper lines.
• Zinc-plated iron components for hardness and corrosion protection on threaded areas.
• Plating reduces oxidation that can cause leaks or seizure during disassembly.

How do the O-rings and beadlock design improve leak prevention?

The O-rings in this set use a beadlock-style seating which helps the seal stay captured under hose pressure and vibration. That design makes installation more forgiving while maintaining a dependable seal when torqued to spec.

• Beadlock seat holds the O-ring in place during assembly and service.
• Spare O-rings included to replace compressed or aged seals during repairs.
• Works with the included clamps and threaded fittings to form a secure joint.

Which applications and systems can this kit serve?

The TRUCFUSION set fits common automotive and small commercial AC hoses that use #6, #8, and #10 fittings and R134a service valves. It’s intended as a general service kit, not for high-pressure industrial refrigeration beyond its specified thread sizes and valve types.

• Automotive A/C line repair and replacement for passenger vehicles and trucks.
• Light-commercial HVAC hose work and quick-service jobs requiring multiple angles.
• Preventive maintenance kits for service vans, garages, and mobile technicians.

Who this kit is for: TRUCFUSION’s 42-piece AC fitting set is aimed at mechanics, HVAC technicians, and knowledgeable DIYers who need a single, organized kit for common refrigerant line work. If you regularly service R134a systems or want a ready supply of threaded fittings, O-rings and clamps for on-the-spot repairs, this set reduces trips to the parts counter. It’s not a substitute for system-specific adapters or certification-required refrigerant service tools, but it covers the majority of hose, angle and valve needs encountered in routine automotive and light-commercial AC work.
