Midland Industries 848040 Sch 80 Pvc Pipe Cap 4 in Fpt

Product Description

The MIDLAND INDUSTRIES 848040 is a Schedule 80 PVC pipe cap with a 4-inch female pipe thread (FPT) connection. It is used to terminate or seal the end of a threaded pipe run in plumbing and industrial piping systems. The Schedule 80 wall thickness provides greater pressure tolerance and impact resistance compared to Schedule 40 fittings, making it appropriate for more demanding installations. Plumbers, pipefitters, and mechanical contractors install this type of cap when capping off branch lines, pressure-testing systems, or closing unused ports in a piping network.

This cap is suited for residential and commercial plumbing applications where PVC Schedule 80 fittings are specified. It is commonly installed in water distribution, chemical handling, and irrigation systems where threaded connections are preferred. The 4-8 thread designation corresponds to a 4-inch nominal pipe size with 8 threads per inch, consistent with NPT standards for this pipe diameter.

Key Features

• Schedule 80 PVC construction for higher pressure ratings compared to Schedule 40
• 4-inch FPT connection threads onto male-threaded pipe ends
• 4-8 thread form consistent with standard NPT thread dimensions for 4-inch pipe
• PVC material offers corrosion resistance and compatibility with a wide range of fluids
• Terminates or seals threaded pipe runs cleanly without additional fittings

Compatibility

Designed as an OEM-style replacement and standard fitting for Schedule 80 PVC threaded piping systems using 4-inch female pipe thread connections.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working with Schedule 80 PVC systems. Apply an appropriate thread sealant or PTFE tape to the male threads before installing the cap. De-pressurize and drain the line completely before removing or installing any threaded caps. Follow applicable IPC and local plumbing code requirements for pressure testing and material specifications.
