Midwest 84815 Air Tank Valve 1/8 Inch Mpt Zinc

Product Description

The MIDWEST 84815 is a zinc-finished air tank valve with a 1/8-inch male pipe thread (MPT) connection. It is designed to control airflow in compressed air tanks and pressure vessels used across HVAC, pneumatic tool, and general mechanical service applications. The MPT fitting threads directly into a female-tapped port on the tank, providing a secure, pressure-rated seal. Licensed HVAC technicians, plumbers, and general mechanical contractors commonly install this type of valve during tank maintenance, pressure system assembly, or replacement of a failed or leaking original valve.

This valve is suited for residential and light commercial compressed air systems, portable air tanks, and shop compressor setups where a small-format MPT valve is required. The 1/8-inch nominal size makes it appropriate for low-volume ports on smaller tanks and pneumatic line fittings. It is a standard replacement item kept in service vans and shop inventories for quick field repairs.

Key Features

• 1/8-inch nominal MPT connection threads directly into female-tapped tank ports
• Zinc finish provides corrosion resistance in typical shop and field environments
• Compact form factor suited for small-format air tanks and pneumatic assemblies
• Standard MPT thread pattern is widely compatible with common pipe fittings

Compatibility

Designed as an OEM-style replacement air tank valve for compressed air tanks and pressure vessels fitted with a 1/8-inch female pipe thread port.

Installation Notes

Installation should be performed by a qualified technician. Before servicing, fully depressurize and bleed the air tank to zero psi to prevent injury. Apply thread sealant tape or pipe compound to the MPT threads before installation to ensure a leak-free seal. Tighten to snug fit using an appropriate wrench — do not overtighten zinc-body fittings. Verify the system holds pressure before returning it to service.
