First line laundry is charging $15.95 for a 3/4", 6 foot hose.
You can get a 3/4", 6 foot hose from Parts distributors for $10.80, and the quality is top notch. Heavy duty solid brass fittings and Goodyear pneumatic hose primarily used for things like bulldozers and backhoes.
Check them out. They don't have a website, but many of their parts are price friendly.
My only complaint is that they put you on hold a lot when you call.
Tell them Mr Machine recommended them.
Like I always say...."It all comes out in the wash"....
