Why Use Both 1/4" and 3/8" Fittings?

Pressure washer systems often combine components with different fitting sizes.

These fittings are designed to accept only certain styles of plugs, ensuring a secure and reliable connection. This kit includes both so you can:

• Equip multiple components in your system without buying separate adapters

• Mix and match brands or accessories with confidence

• Maximize compatibility between tools, hoses, and add-ons

• Standardize your gear for professional use or team setups, distinguishing between various types of lines to prevent issues like contamination and ensure proper functionality

With both sizes in one package, you can upgrade your whole system in one go.
