Air-Conditioning Quick Coupler and Joint Set – Multi-Fitting Brass Adapter Kit

Brief Overview

This is a practical, ready-to-use air-conditioning service kit designed for technicians working with refrigerant systems across multiple vehicle platforms and A/C unit specifications. The set combines brass quick-coupler bodies, threaded adapters, flexible service hoses, and 90° elbow fittings to handle the variety of connection standards encountered in automotive and commercial A/C servicing. Resellers stocking this kit benefit from offering customers a single solution that reduces the need to purchase individual components separately. For shops that also work with high/low pressure quick couplers and adjustable quick joints, this adapter set complements those offerings by providing the adapter solutions that bridge different fitting standards.

Key Features

• Dual-color flexible service hoses – Red and blue sleeves for high/low pressure identification; brass male fittings at each end
• Multiple threaded adapter formats – Covers common A/C standards: 5/16–32, 7/16–20, 3/8–20, 3/8–24, M14×1.5, and T1/2–16 threads
• 90° elbow couplers – Three right-angle brass adapters with knurled caps for hand-tight connections; compact design saves space in tight engine bays
• Quick-coupler body with locking sleeve – Female coupler with silver-finish locking sleeve for secure service port engagement
• Sealed connections – Select adapters include black rubber O-rings to prevent refrigerant leakage
• All-brass construction – Durable, corrosion-resistant brass throughout; bright finish with select silver-plated components
• Knurled surfaces for grip – Hand-wrench flats on hex adapters and knurled cylindrical caps ensure reliable tightening without slipping

Business Advantages for Resellers

• High-velocity SKU: A/C service kits move quickly during warm seasons; stock rotation is predictable.
