Abstract
A hose coupling for use in vehicle air conditioning ('A/C') systems comprises a nipple at the end of a metal tube, a tubular seal insert, and a crimp collar. The seal insert includes a tubular retainer and at least one annular sealing element made of elastomeric material integrally joined to the retainer. The sealing element protrudes radially inwardly from an inner diameter surface of the retainer such that when the sealing element is telescoped over the nipple, the sealing element will effect a seal with an outer diameter surface of the nipple. The sealing element also protrudes radially outwardly from an outer diameter surface of the retainer such that when an end portion of a hose is telescoped thereover, the sealing element will effect a seal with an inner diameter surface of the hose end portion.
