Midland Industries 29900 Mold Coolant Qd Male Pipe Plug Brass

Product Description

The MIDLAND INDUSTRIES 29900 is a mold coolant quick-disconnect male pipe plug designed for hydraulic cooling line applications. Constructed from brass, this plug features a 1/4-inch body and a 1/8-inch male NPT connection with a 1/8-27 thread standard. It is rated for pressures up to 200 psi and handles temperatures ranging from -90 degrees F to 400 degrees F, making it suitable for demanding thermal cycling environments. Industrial maintenance technicians and mold cooling system specialists install this fitting when disconnecting or capping coolant circuit lines during mold changeouts or maintenance procedures.

This plug is used in injection mold cooling systems, hydraulic quick-disconnect circuits, and related industrial fluid-transfer applications. It is appropriate for both light manufacturing and heavy industrial environments where reliable, leak-free line closure is required at the mold coolant interface. The compact brass construction makes it a standard choice for coolant manifold work where space and material compatibility are considerations.

Key Features

• Brass construction provides corrosion resistance in water-based and oil-based coolant systems
• 1/8-27 NPT thread ensures a standard, secure pipe connection
• 200 psi pressure rating supports typical mold cooling circuit operating pressures
• Wide temperature range of -90 degrees F to 400 degrees F accommodates thermal cycling demands
• Quick-disconnect plug design allows fast line isolation without tools

Compatibility

Designed as an OEM-style replacement or service fitting for 1/4-inch body mold coolant quick-disconnect systems using 1/8-inch male NPT connections.

Installation Notes

Installation is typically performed by industrial maintenance technicians or plumbing professionals familiar with hydraulic quick-disconnect fittings. Depressurize and drain the coolant circuit fully before installing or removing any fittings to prevent fluid release or injury. Apply appropriate thread sealant to the NPT threads per the system manufacturer's recommendations. Follow applicable facility safety and fluid-handling procedures during service.
