Lisle Jiffy-tite Disconnect Set 4-Piece Low-Profile for Fuel & Vacuum Lines — Molded Case

This low-profile Jiffy-tite disconnect kit gives technicians and DIYers a controlled way to disengage hose lines from tight-access quick-connect fittings. Each tool has precisely shaped teeth sized to fit the narrow tolerances of Jiffy-tite connectors so the line can be pulled free without harming the connector or its clip. The set comes in a molded storage case and includes the most commonly used sizes for domestic automotive and equipment applications.

How does the Lisle 22990 allow line removal in cramped engine bays?

The tools feature a low-profile form and narrowly spaced teeth that slide into the small gap between connector and hose. Once inserted and rotated, the tool disengages the locking mechanism so the hose can be withdrawn without removing the clip or disassembling nearby components.

• Low-profile shape for limited clearance work
• Tooth geometry designed to match Jiffy-tite tolerances
• Rotation action releases the line cleanly
• Reduces need for clip removal or connector replacement

What sizes are included and what applications do they cover?

The set contains four disconnects sized 3/8", 1/2", 5/8"-30% and 5/8"-39%, covering a broad range of Jiffy-tite quick-connect fittings found on fuel, vapor, coolant, and vacuum lines. These sizes handle most common automotive and small-equipment connections; note that the larger 3/4" Jiffy-tite tool is sold separately.

• 3/8" — smaller fuel and vapor lines
• 1/2" — mid-size fuel and vacuum lines
• 5/8"-30% and 5/8"-39% — larger lines and varying hose wall profiles
• Molded case keeps the set organized and protected

Will using this set damage Jiffy-tite fittings or retaining clips?

No — the Lisle disconnects are shaped to release the hose without deforming the connector or clip when used properly. The tools are intended to preserve reusable components so you can reconnect lines or replace only what’s necessary, saving time and parts costs.

• Precision teeth avoid gouging or bending connector lips
• Enables reuse of retaining clips and fittings
• Reduces downtime and replacement parts expense
• Best practice: steady insertion and small rotation motion

Who this is for: The Lisle 22990 set is aimed at mechanics, fleet technicians, and home mechanics who regularly service vehicles and small engines with Jiffy-tite quick-connect systems. It’s useful for anyone needing a compact, reliable way to separate hoses in tight spaces without sacrificing reusable fittings—especially in fuel and vacuum line work, HVAC service on small equipment, and routine maintenance where preserving clips and connectors speeds repairs.
