Hose joint with adhesive
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 method of creating a hose joint assembly, the method comprising the steps of:
cutting a first hose disposed on a fitting and thereby scoring an imperfection in a surface of the fitting;
removing the first hose from the fitting;
applying an adhesive to at least one of an outer surface of the fitting or an inner surface of a second hose, wherein the adhesive is a microencapsulated adhesive that is a first fluid with microcapsules containing a second fluid dispersed in the first fluid;
sliding the second hose onto the fitting;
at least partially filling the imperfection with the adhesive;
rupturing the microcapsules with pressure to mix the first fluid with the second fluid; and
curing the adhesive once the first fluid and the second fluid are mixed to bond the fitting and the second hose together to seal a joint between the fitting and the second hose and to prevent a fluid flowing through the joint from leaking from the joint.
2. The method as recited in claim 1 wherein the step of sliding the second hose ruptures the microcapsules.
3. The method as recited in claim 1 wherein the first fluid comprises a first epoxy precursor and the second fluid in the microcapsules is a second epoxy precursor, and the microcapsules containing the second fluid are suspended in the first epoxy precursor.
4. The method as recited in claim 1 wherein the second hose comprises an inner layer and an outer layer.
5. The method as recited in claim 4 wherein the inner layer comprises an elastomer and the outer layer comprises a polymer.
6. The method as recited in claim 4 wherein the inner layer comprises ethylene propylene diene monomer and the outer layer comprises plastic.
7. The method as recited in claim 1 wherein the fitting is fluidly connected to at least one of a vehicle transmission or a radiator.
8. The method as recited in claim 1 wherein the fitting is metal and the second hose is rubber.
9. A method of creating a hose joint assembly, the method comprising the steps of:
cutting a first hose disposed on a fitting and thereby scoring an imperfection in a surface of the fitting;
removing the first hose from the fitting;
applying an adhesive to at least one of an outer surface of the fitting or an inner surface of a second hose comprising an inner layer and an outer layer, wherein the adhesive is a microencapsulated adhesive that is a first fluid with microcapsules containing a second fluid dispersed in the first fluid, and the fitting is fluidly connected to at least one of a vehicle transmission or a radiator;
sliding the second hose onto the fitting, wherein the step of sliding the hose ruptures the microcapsules;
at least partially filling the imperfection with the adhesive;
rupturing the microcapsules with pressure to mix the first fluid with the second fluid; and curing the adhesive to bond the fitting and the second hose together to seal a joint between the fitting and the second hose and to prevent a fluid flowing through the joint from leaking from the joint.
10. The method as recited in claim 9 wherein the first fluid comprises a first epoxy precursor and the second fluid in the microcapsules is a second epoxy precursor, and the microcapsules containing the second fluid are suspended in the first epoxy precursor.
11. The method as recited in claim 9 wherein the inner layer comprises an elastomer and the outer layer comprises a polymer.
12. The method as recited in claim 11 wherein the inner layer comprises ethylene propylene diene monomer and the outer layer comprises plastic.
