Valve Configuration
PEX Connection
The PEX end connects to compatible tubing using the appropriate approved connection method for the selected PEX system.
Full-Port Ball
The internal full-port opening helps minimize restriction and maintain system flow when the valve is fully open.
Male NPT Connection
The MNPT end threads directly into a compatible female NPT fitting, valve, manifold, or equipment connection.
Construction Details
Midland Lead-Free Brass PEX x MNPT Ball Valves are manufactured from corrosion-resistant forged brass for dependable mechanical strength and long service life.
The full-port chrome-plated brass ball and PTFE seats provide smooth quarter-turn operation and reliable shutoff performance.
A blowout-proof stem enhances durability, while the zinc-plated steel lever handle with vinyl grip provides fast manual control between fully open and fully closed positions.
Why Choose a PEX x MNPT Ball Valve?
PEX-to-Threaded Transition
- Combines PEX and threaded connections in one valve
- Connects PEX tubing to female NPT components
- Reduces the need for a separate adapter
- Useful for equipment and manifold connections
- Simplifies mixed-connection piping layouts
Fast Quarter-Turn Shutoff
- 90° lever operation
- Quick opening and closing
- Positive manual shutoff
- Easy visual valve-position indication
- Suitable for system isolation
Full Port Design
High-Flow Path
The full-port configuration uses a larger internal opening intended to help maintain flow through the valve.
Reduced Restriction
The larger bore helps minimize pressure loss compared with valves that use a smaller internal opening.
Typical Applications
PEX Plumbing Systems
- Residential water distribution
- Commercial plumbing
- PEX supply piping
- Branch isolation
- Fixture and equipment connections
Hydronic & Threaded Equipment
- Hydronic heating systems
- Manifolds
- Pumps
- Mechanical equipment
- Compatible female NPT connections
PEX & Threaded Installation
Install the PEX connection using compatible tubing and the approved connection method specified for the system.
Apply appropriate thread sealant or PTFE tape to the male NPT connection before threading it into a compatible female NPT component.
Our plumbing specialists can help review your PEX tubing size, male NPT connection, potable water requirements, hydronic application, and installation needs before you order.
