Description
Schedule 40 PVC Bushing (MIPT x FIPT)
Schedule 40 PVC Threaded Reducer Bushings provide a compact way to reduce between two different threaded connection sizes in compatible cold-water pressure piping systems.
Featuring a male iron pipe thread (MIPT) on the outside and a female iron pipe thread (FIPT) on the inside, this fitting threads into a compatible female connection while accepting a smaller male threaded pipe, nipple, valve, fitting, or equipment connection. Durable PVC construction provides corrosion resistance, lightweight handling, and dependable performance in potable water, irrigation, pool, spa, and other compatible pressure piping applications.

Connection Configuration
Male Threaded End
The MIPT exterior threads into a compatible female threaded fitting, valve, or equipment connection.
Female Threaded Opening
The FIPT opening accepts a smaller compatible male-threaded pipe, nipple, fitting, valve, or equipment connection.
Construction Details
The bushing is manufactured from high-quality Schedule 40 PVC for resistance to corrosion, chemicals, scaling, and environmental conditions commonly encountered in compatible cold-water pressure systems.
The male threaded exterior allows the bushing to install into a larger female threaded connection, while the smaller internal female thread provides the reduced outlet or connection size.
This compact configuration combines size reduction and threaded transition functions in a single fitting, helping simplify compatible piping layouts.
Why Choose a MIPT x FIPT Bushing?
Compact Threaded Reduction
- Reduces between two threaded sizes
- Installs directly into a larger female thread
- Provides a smaller female threaded opening
- Can reduce the need for multiple adapters
- Useful where installation space is limited
PVC Pressure-Piping Benefits
- Corrosion-resistant construction
- Lightweight material
- Resistant to many common chemicals
- No solvent-weld joint required at the bushing
- Suitable for compatible cold-water pressure applications
Typical Applications
Water & Irrigation Systems
- Potable water distribution
- Residential cold-water piping
- Irrigation systems
- Threaded valve connections
- Pipe-size transitions
Pool, Spa & Commercial Systems
- Swimming pool plumbing
- Spa circulation systems
- Commercial cold-water piping
- Pump and equipment connections
- General threaded Schedule 40 PVC systems
Threaded Installation
Verify both nominal thread sizes before installation. Confirm that the MIPT size matches the receiving female threaded connection and that the FIPT opening matches the intended smaller male-threaded component.
Use an appropriate thread-sealing method compatible with PVC and the intended application. Start all threaded connections by hand to help prevent cross-threading.
Tighten only as required to obtain a secure, leak-resistant connection. Excessive tightening can place unnecessary stress on PVC threads and may damage the bushing or mating fitting.
Verify the completed installation for proper alignment and sealing before placing the piping system into normal service.

Our plumbing specialists can help review your male and female thread sizes, mating fittings, pressure application, and installation requirements before you order.

What is a Schedule 40 PVC MIPT x FIPT bushing used for?
It is used to reduce from a larger female threaded connection to a smaller male-threaded component in a compatible pressure piping system.
What does MIPT mean?
MIPT means Male Iron Pipe Thread. The exterior male thread screws into a compatible female threaded connection.
What does FIPT mean?
FIPT means Female Iron Pipe Thread. The internal threaded opening accepts a compatible male-threaded component.
How does this bushing reduce pipe size?
The larger exterior male thread installs into a larger female connection while the smaller internal female thread accepts the reduced-size male-threaded component.
Does this fitting require solvent cement?
No. This version uses threaded connections on both sides rather than solvent-weld connections.
Should PVC threaded fittings be overtightened?
No. Excessive tightening can stress or damage PVC threads and fitting bodies. Connections should be started by hand and tightened only as necessary.
Can this fitting be used for potable water?
The supplied product information identifies this fitting for potable water applications and references NSF/ANSI 61 among its applicable standards.
Can it be used in irrigation, pool, and spa systems?
Yes. Irrigation, pool, and spa plumbing are among the listed applications for this fitting.
What standards are referenced for this fitting?
The supplied product information references ASTM D2466, ASTM D1784, CSA B137.3, NSF/ANSI 14, NSF/ANSI 61, cNSF, and cUPC.
What should I verify before ordering?
Confirm both nominal thread sizes, the MIPT x FIPT configuration, the mating female and male threaded components, and compatibility with the intended Schedule 40 PVC pressure system.
