Lisle STC Disconnect Set, 4-Piece (6/8/10/12mm) Angled-Head Tools for Tight Spaces

If you work on fuel, hydraulic, power steering or cooler lines that use STC quick-disconnect fittings, the Lisle 38500 gives you four purpose-sized tools with angled heads and comfortable grips to speed up service tasks. The set includes 6, 8, 10 and 12mm sizes and is built to access confined spaces where straight tools struggle. It’s commonly used on Ford 6.0L and 7.3L high-pressure oil lines as well as many Case, International and John Deere tractors.

How does the angled head design help in cramped engine bays?

The angled head provides clearance that lets you reach fittings located behind manifolds, brackets or bundled hoses. Instead of fighting space limitations with pliers or improvised tools, the Lisle heads slide into the fitting retaining collar for positive engagement. That makes disconnects faster and reduces the risk of damaging surrounding lines or connectors.

• Angled head clears obstructions for easier access
• Reduces need to remove other components first
• Minimizes accidental damage to adjacent lines

Which vehicle lines and fittings is this set compatible with?

This set is intended for STC-style quick-disconnect fittings commonly found on high-pressure oil, fuel, hydraulic, power steering, cooler and brake lines. It lists specific compatibility with Ford 6.0L and 7.3L high-pressure oil systems, and it also fits many Case, International and John Deere tractor fittings. Confirm fitting style and size before use to ensure correct engagement.

• Works on Ford 6.0L/7.3L high-pressure oil lines
• Compatible with many Case, International, John Deere tractors
• Suitable for fuel, hydraulic, cooler, power steering and brake lines

What sizes are included and how do they cover typical jobs?

The kit contains four driver-shaped disconnect tools sized 6mm, 8mm, 10mm and 12mm to match a broad range of common STC fittings. These incremental sizes allow a precise fit across small to medium quick-disconnect collars used in automotive and agricultural systems. Having the right size on hand reduces slips and speeds up service cycles.

• Includes 6, 8, 10 and 12mm sizes for broad coverage
• Each size targets a specific common fitting diameter
• Helps avoid improvised tools that can damage fittings

How does the grip and construction affect usability during extended work?

The tools feature a double-dip grip that improves hand comfort and control during repeated disconnects, which is useful on long jobs or when working in cold, oily conditions. The molded handle profile aids torque transfer while keeping your hand positioned away from hot or sharp components. Durable construction stands up to workshop use without excessive flex.

• Double-dip grip for added comfort and control
• Molded handle reduces hand fatigue during repetitive tasks
• Sturdy tooling resists bending under normal use

Who is this for: The Lisle 38500 STC Disconnect Set is aimed at professional technicians, diesel mechanics, farm equipment service techs and knowledgeable DIYers who regularly service fuel, hydraulic, cooler or power steering systems using STC quick-disconnect fittings. It’s especially useful when working on Ford 6.0L/7.3L high-pressure oil lines or on Case, International and John Deere tractors where space is limited and quick-release access is needed. Keep the set in your shop drawer or service kit to speed routine disconnects while reducing the risk of damage to fittings and lines.
