What is a 3/8 Pressure Gauge Coupler?

A 3/8 pressure gauge coupler is a small brass or stainless steel fitting that connects between the hose and gun of a pressure washer. It has two ends, one with a female thread and the other with a male thread, allowing it to connect with different types of fittings. The main purpose of this coupler is to provide a port where you can attach a pressure gauge to measure the output pressure of your pressure washer.

Additionally, using a coupler can extend the life of your hose by reducing stress caused by twisting or bending.

Factors to consider when buying

When purchasing a 3/8 pressure gauge coupler, there are certain factors that you should keep in mind to ensure that you get the best one for your needs.

Material

The material used in making the coupler is an important consideration as it affects its durability and resistance to corrosion. Brass and stainless steel are two common materials used for making these couplers, both offering excellent durability and corrosion resistance.

Fittings

Make sure to check if the fittings on both ends of the coupler are compatible with your hose and gun. Some may have different thread sizes or types, so it’s essential to double-check before purchasing.
