7-Piece Fuel and Air Conditioning System Connector Set

Brief Overview

Service calls on fuel systems and air conditioning lines require quick, reliable access to the right connector size—every single time. This 7-piece connector set eliminates fumbling with mismatched adapters and keeps your technicians productive. Whether you're working on direct-injection fuel systems, traditional fuel lines, or refrigerant circuits, this set covers the full spectrum of OEM quick-disconnect sizes in European and North American applications. Pair this with a fuel line testing kit for comprehensive diagnostic capability, or combine with air-conditioning quick couplers for a complete service station setup.

Key Features

• Seven Standard Sizes: 1/4", 5/16", 3/8", 1/2", 5/8", 3/4", 7/8" — covers the vast majority of OEM fuel and A/C quick-disconnect fittings
• Color-Coded Identification: White adapters with molded size markings enable rapid size selection under shop conditions
• Integrated Locking Tabs: Black inner sleeves with positive engagement prevents accidental disconnection during line servicing
• Durable Plastic Construction: Lightweight, chemical-resistant polymer withstands exposure to fuel, oil, and refrigerant without degradation
• Organized Storage Holder: Circular mounting plate with hanging hole keeps all seven adapters accessible and organized on the shop wall or tool cart
• No Setup Required: Ready to use immediately; no assembly or adapter configuration needed

Why Resellers Choose This Set

High-Frequency Demand: Fuel system and A/C servicing is a recurring revenue driver in any independent shop or quick-lube facility. Technicians will use this set multiple times per day.
