ABSTRACT:
A strong joint for hoses for the cooling and crankcase ventilation systems of vehicles is made between a hose 1 and a branch by inserting the flared end 3 of a rigid cylindrical insert 4 into a hole 9 in the hose 1 to distort the margin around the hole. A second hose 6 is then positioned over the insert 4 so that its end abuts the margin of the hole and the joint is sealed and secured by an encapsulation which is vulcanized in situ.
A curable polymeric liner 5 may be sandwiched between the insert 4 and the spout 6 and also vulcanized to act as a bond.
The second hose may be omitted, leaving the insert as a projection to which a second hose may be fitted by other means.
