TPE medical tubing with single-barb fitting is stronger than adhesive-bonded PVC


Eldon James Corp., a supplier of medical tubing and fittings, has published the results of tests it conducted to determine the toughness of tubing produced from Medalist thermoplastic elastomers (TPEs), manufactured by Teknor Apex Co., and the durability of connections between this tubing and single-barb luer fittings.

In pull-apart tests of more than 1000 assemblies, the connections typically did not fail until forces greater than 8 lb were applied, more than double the requirement set by Eldon James' customer, according to Mark Timbrook, Marketing Director. In burst tests, the TPE tubing withstood average pressures of 500 psi before failure.
