Can this 5 n 1 quick connect be used on a pressure washer line?

Pressure washers are at a really high pressure I doubt a fitting for compressed air is safe

Does this come in a 3/8 female to 3/8 female body?

We have part# 1758, which is 3/8 by 3/8 FNPT

We’ll this work with P stile fittings

No, P style is 3/8 automotive plug. This coupler is 1/4:.

Does this come as pictured above - with protective black bumpers?

Mine did not. But then again, when I bought mine, the photos of the item did not show those black bumpers. Makes me think that this is a different/upgraded/later model.
