Product review (1 stars): not 3/8 inch
Our new washer and steam dryer came with rubber hoses 3/8 inch inside diameter, and a Y connecter the same size that feeds both the washer and the dryer. Hoping to upgrade and avoid a sudden leak (been there), I ordered braided stainless Loyal hoses from Amazon rather than accept the 1/4 braided hoses our local big box carries, ONLY because Loyal describes theirs as 3/8 inch inside diameter.

They arrived on time, well packaged, but with the same 1/4-inch opening as the big box hoses (not that the big boxes list the reduced ID). It's one thing to be forced to choose between reduced flow rate with longer wash cycle vs rubber hoses more likely to spring a leak. It's another to be conned by a false product description. Amazon should include actual inside diameter on all their hoses.
