Dura Plast 503-005 Pvc Schedule 40 Mht X Mpt Adapter

Product Description

The DURA PLAST 503-005 is a Schedule 40 PVC adapter designed to transition a male pipe thread (MPT) connection to a male hose thread (MHT) connection. One end features 3/4 inch MHT compatible with standard US garden hose threads, while the other end is a male national pipe thread (MPT). Built from Schedule 40 PVC, this fitting handles typical residential and light commercial water service pressures while resisting corrosion. Plumbers and irrigation installers use this adapter to connect threaded PVC pipe runs or fittings to hose-threaded equipment, valves, or outlets.

This adapter is suited for potable water supply lines, irrigation systems, outdoor hose bibs, and general plumbing applications where a pipe thread-to-hose thread transition is needed. It installs in residential and light commercial settings wherever a PVC threaded pipe end must mate with a garden hose or hose-thread fitting. The standard US garden hose thread profile ensures broad compatibility with common hose fittings, nozzles, and valves available in the field.

Key Features

• Transitions MPT (male national pipe thread) to MHT (male hose thread) in a single fitting
• 3/4 inch MHT end is compatible with standard US garden hose threads
• Schedule 40 PVC construction offers corrosion resistance and durability in water service applications
• Threaded on both ends for tool-assisted installation without adhesive or solvent welding

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 PVC threaded piping systems requiring a male pipe thread to male hose thread transition.

Installation Notes

This fitting is typically installed by licensed plumbers or experienced irrigation technicians. Shut off the water supply and relieve line pressure before installation. Apply thread sealant tape or pipe dope to the MPT threads before making up the connection, and tighten with an appropriate wrench to avoid cracking the PVC body. Follow all applicable local plumbing codes, including IPC requirements for threaded fittings in pressurized water systems.
