Schedule 80 PVC Coupling (FIPT x FIPT)

Schedule 80 PVC Female Threaded Couplings provide a durable straight-line connection between compatible male-threaded components in pressure piping systems.

Featuring Female Iron Pipe Thread (FIPT) connections on both ends, this coupling allows two male-threaded pipes, nipples, fittings, valves, or equipment connections to be joined in-line without solvent welding at the coupling itself. Heavy-wall Schedule 80 PVC construction provides excellent corrosion and chemical resistance for potable water, industrial, commercial, irrigation, and other compatible pressure piping applications.

Connection Configuration

First FIPT Connection

The first female threaded opening accepts a compatible male-threaded pipe, nipple, fitting, valve, or equipment connection.

Second FIPT Connection

The opposite female threaded opening accepts another compatible male-threaded component to complete the straight in-line connection.

Construction Details

The coupling is manufactured from high-quality Schedule 80 PVC, providing increased wall thickness and dependable durability for compatible pressure piping applications.

Precision-molded female threads on both ends provide mechanical connections to compatible male-threaded components without requiring solvent cement at the coupling itself.

The straight-through design provides a compact way to join threaded piping components while maintaining the corrosion resistance and lightweight handling advantages of PVC.

Threaded Installation

Verify both nominal female thread sizes before installation and confirm compatibility with the intended male-threaded components.

Use an appropriate thread-sealing method compatible with PVC and the intended application. Start each threaded connection 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 female threads and may damage the fitting body.

Confirm proper alignment, operating pressure, temperature requirements, and chemical compatibility before placing the piping system into service.

Frequently Asked Questions

What is a Schedule 80 PVC FIPT x FIPT coupling used for?

It is used to join two compatible male-threaded components in a straight Schedule 80 PVC pressure piping connection.

What does FIPT mean?

FIPT means Female Iron Pipe Thread. Both openings contain internal threads designed to accept compatible male pipe threads.

Does this fitting require solvent cement?

No. This version uses threaded connections on both ends rather than solvent-weld socket connections.

What can connect to this coupling?

Compatible male-threaded pipe, nipples, fittings, valves, instruments, or equipment connections may be used where appropriate for the system.

Should Schedule 80 PVC female threads be overtightened?

No. Excessive tightening can stress or damage the PVC threads or fitting body. Connections should be started by hand and tightened only as required.

Can this fitting be used for drinking water systems?

The supplied product information identifies NSF/ANSI 61 compliance for drinking water system components.

What does NSF/ANSI 14 cover?

NSF/ANSI 14 applies to plastic piping system components and related materials.

What ASTM standards are referenced?

The supplied product information references ASTM D1784 and ASTM F1970.

What CSA standard is referenced?

The supplied product information references CSA B137.3 for rigid PVC pipe and fittings used in pressure applications.

What should I verify before ordering?

Confirm both nominal female thread sizes, mating male-threaded components, pressure requirements, temperature requirements, chemical compatibility, and intended application.
