Rubber 7ft (84inches) low pressure hose.  Used for the primary 2nd stage regulator in a long-hose set-up.  This is the long hose.  This hose gets used a lot, so we recommend inspecting it often and replacing it every 5 years or sooner if you notice wear.

You'll want a bolt snap to manage this.  Guess what we also sell?!  NO! We don't sell cakes!  We sell bolt snaps.  All kinds of bolt snaps, no kinds of cake!
