Description
When Both Lines End in a Socket
Many modern vehicles use SAE J2044 quick-connect fittings across their air breather, vacuum, PCV, coolant, transmission, EVAP, and EFI fuel lines.
Delete a component or build a custom run, and you’re left with two lines that both end in female couplers, with no factory part to join them. Your options were cutting in and converting to AN, or chasing a dealer part that may not exist.
This is that part. Snap a female quick connect fitting onto each end. Done.
Built to Last
In a J2044 connection, the female coupler’s O-rings seal against the male tube. Stainless gives you a harder, corrosion-resistant surface that won’t degrade like OEM plastic.
Sizing
| Part | End A | End B | Type |
| QMM-05 | 5/16″ (7.89mm) | 5/16″ (7.89mm) | Equal |
| QMM-05-06 | 5/16″ (7.89mm) | 3/8″ (9.49mm) | Reducer |
| QMM-06 | 3/8″ (9.49mm) | 3/8″ (9.49mm) | Equal |
| QMM-06-M10 | 3/8″ (9.49mm) | M10 (9.89mm) | Reducer |
| QMM-M10 | M10 (9.89mm) | M10 (9.89mm) | Equal |
Measure before you order. 3/8″ (9.49mm) and M10 (9.89mm) are only 0.4mm apart and easy to confuse. Measure the OD of your mating female coupler’s barb to confirm.
Features and Benefits
- Union fitting with male SAE J2044 ends on both sides, connecting two female SAE J2044 quick connect fittings.
- Ideal for joining, looping, or splicing OEM quick connect hose lines, including transmission cooler lines.
- Reducer options step a smaller line up to a larger one without re-terminating either side.
- Durable stainless steel construction.
