Hose joint with adhesive

Abstract

A hose joint assembly includes a fitting, a hose receivable onto the fitting, and an adhesive for bonding the hose and the fitting together. For example, the adhesive is a microencapsulated two-part epoxy adhesive that functions as a lubricant when assembling the hose onto the fitting before curing.

1 . A hose joint assembly comprising:
 a fitting;   a hose receivable onto the fitting; and   an adhesive for bonding the hose and the fitting together.   
     
     
         2 . The assembly as recited in  claim 1 , wherein at least one of the hose or the fitting includes an imperfection that forms a void in a wall of the hose of the fitting, wherein the adhesive at least partially fills the imperfection. 
     
     
         3 . The assembly as recited in  claim 2 , wherein the imperfection comprises a score mark. 
     
     
         4 . The assembly as recited in  claim 1 , wherein the adhesive comprises a microencapsulated adhesive. 
     
     
         5 . The assembly as recited in  claim 1 , wherein the adhesive comprises cyanoacrylate. 
     
     
         6 . The assembly as recited in  claim 1 , wherein the adhesive comprises a first epoxy precursor and microcapsules containing a second epoxy precursor, where the microcapsules are suspended within the first epoxy precursor. 
     
     
         7 . The assembly as recited in  claim 1 , wherein the hose comprises a plurality of layers. 
     
     
         8 . The assembly as recited in  claim 7 , wherein at least one of the plurality of layers comprises elastomer. 
     
     
         9 . The assembly as recited in  claim 7 , wherein at least one of the plurality of layers comprises ethylene propylene diene monomer elastomer. 
     
     
         10 . The assembly as recited in  claim 7 , wherein at least one of the plurality of layers comprises elastomer and another of the plurality of layers comprises plastic. 
     
     
         11 . The assembly as recited in  claim 1 , wherein the fitting is fluidly connected with at least one of a vehicle transmission or a radiator. 
     
     
         12 . A hose joint assembly comprising, from inside out, a metal fitting defining a conduit there through, a microencapsulated adhesive layer, an elastomer hose layer bonded to the metal fitting by the microencapsulated adhesive layer, and a polymer hose layer bonded directly to the elastomer hose layer. 
     
     
         13 . The hose joint assembly as recited in  claim 12 , wherein the microencapsulated adhesive layer comprises a two-part epoxy, the elastomer hose layer includes ethylene propylene diene monomer, and the polymer hose layer includes plastic. 
     
     
         14 . A method of repairing a hose joint assembly, comprising the steps of:
 (a) removing a hose that is secured on a fitting;   (b) applying a lubricant/adhesive to at least one of the outer surface of the fitting or to an inner surface of a replacement hose; and   (c) sliding the replacement hose onto the fitting and curing the lubricant/adhesive.   
     
     
         15 . The method as recited in  claim 14 , wherein said step (a) includes cutting the hose. 
     
     
         16 . The method as recited in  claim 15 , wherein said step (a) includes scoring an outer surface of the fitting to thereby form a score mark. 
     
     
         17 . The method as recited in  claim 16 , wherein said step (b) includes at least partially filling the score mark with the adhesive/lubricant.
