Valve Configuration

PEX Barb Connection

The PEX barb end connects directly to compatible PEX tubing using the appropriate crimp-style installation system.

Full-Port Ball

The internal full-port opening helps minimize restriction and pressure loss when the valve is fully open.

Female NPT Connection

The FNPT end accepts a compatible male-threaded pipe, nipple, fitting, or equipment connection.

Construction Details

Midland Lead-Free Brass Ball Valves are manufactured from forged brass to provide dependable mechanical strength, corrosion resistance, and long-term service in compatible plumbing systems.

The full-port ball design provides an open flow path intended to minimize restriction through the valve when fully open.

A vinyl-coated steel lever handle provides smooth quarter-turn operation, allowing the valve to move quickly between fully open and fully closed positions.

Why Choose a PEX x FNPT Ball Valve?

PEX-to-Threaded Transition

Combines two connection styles in one valve
Connects PEX tubing to male NPT components
Reduces the need for separate adapters
Useful for equipment and fixture connections
Simplifies mixed-material piping layouts

Fast Quarter-Turn Shutoff

90° handle movement
Quick open and close operation
Positive manual shutoff
Easy visual indication of valve position
Suitable for isolation applications

Full Port Design

Full Port

A full-port valve uses a larger internal opening intended to closely match the connected piping and help maintain higher flow through the valve.

Reduced Restriction

The full-port configuration helps minimize pressure drop compared with valves that use a smaller internal flow opening.

Typical Applications

PEX Plumbing Systems

Residential water distribution
Commercial plumbing
PEX supply lines
Branch isolation
Fixture and equipment connections

Threaded Equipment Connections

Water heaters
Manifolds
Pumps
Plumbing equipment
Compatible male NPT components

Pressure Rating

The supplied product information identifies these valves with a 400 WOG pressure rating.

Verify the required pressure, temperature, media, PEX system rating, and threaded connection requirements before installation.

Connection & Installation

Install the PEX barb using compatible tubing, rings, and crimp tools specified for the selected PEX system.

Use an appropriate pipe-thread sealant or PTFE tape on the mating male NPT connection. Confirm both connection sizes and system compatibility before installation.
