Excellent instructions.

If I’m using my pressure washer and hoses strictly for washing my car and then putting them back in storage, is it necessary to oil or lubricate the threads and O-rings at all? I have literally been researching this for over week staying up late hours and I still have no idea. Seems like silicone is needed for the O-rings but is not good for the metal on metal threads and the lubrication needed for the threads can dry out the O-rings if it contains petroleum so I’m stuck.. I’m using stainless steel quick connects that have viton O-rings in them. A Flexzilla garden hose, Uberflex pressure washer hose and mtm wand.

O rings are the first to wear out, so it would be beneficial. Just a tiny amount is needed.

Silicone grease is only compatible with non-silicone o-rings! If you use silicone grease on silicone o-rings, they will absorb it, making them swell and become fragile.
