Midland Industries 830003 Sch 80 Pvc Pipe Coupling 3/8 Fpt

Product Description

The MIDLAND INDUSTRIES 830003 is a Schedule 80 PVC pipe coupling with female pipe thread (FPT) connections on both ends, each sized at 3/8 inch. Rated to Schedule 80 wall thickness, this fitting delivers greater pressure tolerance than standard Schedule 40 couplings, making it the right choice where system demands exceed light-duty ratings. The gray PVC construction resists corrosion and chemical attack, common requirements in plumbing and fluid-handling applications. Plumbers and pipefitters install this coupling to join two sections of 3/8-inch pipe in a straight run, using threaded connections for a secure, leak-resistant joint without solvent cementing at the coupling itself.

This coupling is suited for residential and light commercial plumbing systems where Schedule 80 PVC pipe and fittings are specified. Typical installations include cold-water supply lines, irrigation system headers, chemical feed lines, and industrial fluid distribution runs where corrosion resistance and moderate pressure capacity are required. The 3/8-18 thread designation conforms to NPT standards, ensuring compatibility with standard 3/8-inch threaded pipe and fittings across common system configurations.

Key Features

• Schedule 80 wall thickness provides higher pressure rating than Schedule 40 equivalents
• 3/8 in FPT x 3/8 in FPT straight coupling for joining threaded pipe runs
• 3/8-18 NPT thread form for standard compatibility with threaded pipe and fittings
• Gray PVC construction resists corrosion, chemicals, and moisture
• Threaded connection eliminates need for solvent cement at the coupling joint

Compatibility

Designed as a replacement or new-installation fitting for Schedule 80 PVC piping systems using 3/8-inch female pipe thread connections conforming to NPT thread standards.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC requirements. Shut off and depressurize the supply line before removing any existing fittings or making new connections. Apply an appropriate thread sealant or PTFE tape to male threads before hand-tightening and finishing with a strap wrench - avoid pipe wrenches that can crack PVC fittings. Do not over-torque; PVC threads are susceptible to stress fractures under excessive force.
