These are OEM used US Divers and Voit black hoses for the purist.  If you don't want reproduction hoses made of silicone or neoprene these are your best bet.  They are first come first serve while supplies last.  Please note these are used hoses and like ALL neoprene hoses they have a set to them and will show a curve like pictured.  They are serviceable but are not as nice a silicone hoses.  You will get 1 pair of hoses for $25.00 plus shipping.

Price $20.00 plus 7.00 shipping
