usvehj 800-671 A/C line splice kit 3/8 to No.6 hose — 24-inch rubber hose, leak-resistant on-vehicle repair

The usvehj 800-671 A/C Line Splice Kit is a complete, vehicle-ready repair set that joins a 3/8" A/C line to a No. 6 hose (24") for a secure, leak-resistant restoration without replacing the entire line.

When an automotive A/C hard line is damaged near the firewall, bulkhead, or chafed by road debris, you don’t always need a full line replacement. The usvehj 800-671 kit supplies all components to splice a 3/8" aluminum or steel refrigerant line to a No. 6 rubber hose, letting technicians and competent DIYers make a tight, durable repair on-vehicle. Components are made from copper, steel, aluminum alloy, plastics, and rubber intended to resist corrosion and vibration in typical automotive environments.

How does the splice kit restore a leaking 3/8" A/C line quickly?

The kit replaces the damaged section by creating a mechanical sealed junction between the existing 3/8" hard line and a No. 6 hose. It’s designed for on-vehicle installation so you avoid cutting out and replacing long runs of piping.

• Includes pre-sized fittings, nuts, clips, seal sleeves, and anti-vibration rings for a single repair session.
• No special press tools required — basic hand tools are sufficient.
• Installation follows a straightforward remove-replace-secure sequence, limiting downtime.

What parts come in the 800-671 kit and why are they important?

The kit contains every part needed to form a secure splice, so you don’t have to source fittings individually. Each piece contributes to sealing, clamping, or vibration damping to maintain refrigerant integrity and mechanical stability.

• No. 6 hose — 24 inches of rubber hose sized for common A/C service connections.
• Red fixed nuts (x2) and fittings (x2) that thread to the hard line and hose ends.
• Clips (x4), clip holders (x2), expanded seal sleeves (x2), and anti-vibration tension rings (x2) for secure mounting and leak prevention.

Is the 800-671 kit compatible with my vehicle and safe under operating conditions?

The splice kit is intended for connecting a 3/8" aluminum or steel A/C line to a No. 6 hose, which covers many passenger cars, SUVs, trucks, and light commercial vehicles. Materials are chosen to withstand typical automotive temperature and pressure ranges, though installers should verify system compatibility and follow refrigerant handling rules.

• Works with common 3/8" hard-line configurations and No. 6 hose sizes used in many vehicles.
• Constructed from corrosion-resistant metals and durable rubber for long-term service.
• Not a substitute for components rated for non-standard refrigerants or extreme service conditions; check OEM specifications.

How easy is installation for a DIY mechanic versus a professional?

Installation is designed to be accessible: remove the damaged section, insert the hose, place the seal sleeves and fittings, then tighten and secure clips. Professionals can complete the repair faster, but a careful DIYer with basic tools can perform the splice following the included instructions.

• No specialized crimpers or hydraulic presses required for the basic splice.
• Includes detailed instructions to guide each assembly step and torque points where applicable.
• If uncertain, consult a certified A/C technician to confirm leak-tight results and proper system evacuation/recharge.

Who is this for: The usvehj 800-671 A/C Line Splice Kit is aimed at vehicle owners, independent mechanics, and fleet technicians who prefer repairing a localized A/C line failure rather than replacing entire assemblies. It’s especially useful for budget-conscious repairs, rapid roadside fixes, or shops that need a universal, in-stock solution for common 3/8" to No. 6 hose connections. Always pair the physical splice with correct refrigerant service procedures to ensure safe, long-lasting performance.
