Midland Male Straight Quick Disconnect Plug – MPT
Connect threaded equipment to a compatible quick-disconnect coupler for convenient changes between hoses and accessories.
The plug mates with the coupler’s locking mechanism, allowing the connection to be released without repeatedly unthreading the equipment.
Product Overview & Highlights
Built for Equipment Connections
Keep the threaded end installed while using the plug interface for routine hose or accessory changes.
Choose the matching coupler profile and body size so the assembled connection seats and locks correctly.

Product Guidance
Match the Coupler Interface
Body size identifies the quick-disconnect interface; thread size identifies the equipment connection. Check both when replacing an existing fitting.
Compare the mating profile and locking engagement before putting the assembly into service.
Understand Straight-Through Flow
This connection does not provide automatic shutoff when separated. Isolate the supply and relieve trapped pressure before disconnecting.
Plan for residual fluid at the connection and follow the equipment manufacturer’s shutdown procedure.
Install at the Threaded End
Inspect the receiving female threads and use a thread-sealing method suitable for the equipment and service.
Use the hex wrench flats during installation; avoid gripping or damaging the plug’s mating surface.
Review the Complete Assembly
Check the hose, coupler, seals, and equipment limits together when selecting a connection.
Confirm suitability for the working fluid and temperature, especially when cleaning chemicals or heated water are involved.
Manufacturer Reference
Midland’s pressure-washer catalog identifies these part numbers as male steel plugs. Review the Midland Pressure Washer Catalog PDF for the straight-through QD family and operating limits.
Installation & Selection Considerations
Confirm Body Size
Match the plug’s quick-disconnect body size to the mating coupler.
Check the Threads
Verify the receiving female connection matches the selected MPT size.
Inspect the Profile
Check the plug nose, locking groove, and coupler for wear or damage.
Prepare the Joint
Clean the threads and apply a suitable sealant according to its instructions.
Check Service Limits
Verify pressure, temperature, and fluid compatibility across the assembly.
Relieve Pressure
Isolate the supply before release, then check engagement and leaks on startup.
