Camco Mfg 40143 Water Pressure Regulator 3/4 Inch Garden Hose

Product Description

The CAMCO MFG 40143 is a 3/4 inch male-to-female garden hose thread water pressure regulator designed to reduce incoming water pressure to a safe, consistent operating range of 40 to 50 psi. Built from durable ABS plastic, this regulator installs inline on a standard garden hose connection to protect downstream equipment and hoses from pressure spikes. It is a compact, passive device with no moving parts to program — simply thread it on and it regulates flow automatically. Plumbers, RV service technicians, and irrigation professionals use this part to safeguard pressure-sensitive equipment on job sites and at service connections.

This pressure regulator is suited for residential and light commercial applications where incoming water pressure exceeds safe operating limits for hoses, RV water systems, portable equipment, or irrigation setups. It threads directly onto standard 3/4 inch garden hose fittings, making it compatible with a wide range of hose-fed systems. Typical installations include campsite water hookups, jobsite water supply lines, and outdoor faucet connections where supply pressure may be variable or unknown.

Key Features

• Regulates output pressure to 40 to 50 psi to protect hoses and downstream equipment
• 3/4 inch male x female garden hose thread connection for tool-free inline installation
• ABS plastic construction resists corrosion in outdoor and wet environments
• Passive regulation — no adjustment or programming required
• Helps prevent hose failure caused by excess supply pressure

Compatibility

Designed as an inline replacement or addition for standard 3/4 inch garden hose thread water supply connections on hose-fed equipment, RV water inlets, and portable irrigation systems.

Installation Notes

Installation is performed by a plumber or qualified technician familiar with hose-thread fittings and local plumbing codes. Shut off the water supply at the source before connecting or disconnecting the regulator. Thread the male end onto the supply side and connect the downstream hose to the female end, hand-tightening and then snugging with pliers — do not overtighten ABS plastic fittings. Verify there are no leaks at both connections before returning the system to service.
