Do I need a California-compliant pressure washer?

Yes. If you are using your pressure washer in California, it must be CARB compliant. California law requires that all pressure washers sold and operated in the state to adhere to strict emission standards set by the California Air Resources Board (CARB). The use of non-compliant equipment is subject to fines and confiscation by authorities. Purchasing a non-compliant pressure washer outside of California is not an option if you intend to use it in the state, as it will also need to be CARB compliant. PCE carries a complete line of CARB and EPA compliant pressure washers ready to go right out of the box and stay on the road. To learn all about California compliance, check your equipment, learn more about CARB and what they require, shop all compliant models, and even learn about financing options available to you, head to our California-Compliant Pressure Washers page.

Veloci Brass Coupler 3/8” MPT (24.0070) – Speed Changes & Lasts For Years

Veloci’s 3/8″ Male Pipe Thread (MPT) brass quick-connect coupler creates fast and leak-free connections between high-pressure hoses and pressure washer accessories.</p><p>Constructed from high-quality brass it will last through daily use and is great at handling pressure and creating a seal for high-pressure work.

Brass will eventually corrode and discolor with use and time, but this does not affect its performance or long-term functionality.
Upgrade to a Veloci Stainless Steel fitting if you’re working with a higher PSI and want increased corrosion resistance.

3/8” couplers are commonly used in quick disconnect applications and are often located between a pressure washer pump and spray gun.
Anytime you want to save time during changes Veloci fittings are designed for quick connection and are great on hose lines, lances, or anywhere else on the system where changing tools and accessories often during a cleaning project.

Tip: The male threads (MPT) on a fitting are the external threads. The female threads (FPT) are internal and are on the body of the fitting.

All Veloci fittings are tapered National Pipe Thread (NPT) and will seal with thread interference.

For leak-free NPT fitting installation:

Wrap Teflon tape 4–5 times clockwise around thread

OR

Apply 2–3 drops of Loctite thread sealant
British Standard Pipe (BSP) fittings require more thread sealant and seal differently.
Apply 6–7 wraps of Teflon tape or more thread sealant for leak-free BSP fitting installation.

BSP threads are straight, not tapered, so the threads engage much sooner and do not thread in as far as NPT fittings.
Even though the fittings use a different method to seal they will both create a seal with the correct sealant method during installation.

Specifications:

3/8″ MPT quick-connect brass coupler
High pressure and vibration resistant
Works on hose lines, spray guns, attachments, and more
Compatible with all standard NPT thread systems
Easy to install with Teflon tape or thread sealant
