A unitary molded crosslinked polyethylene tubular connector and method for forming the connector with various end configurations (e.g., molded, belled) is described). The process combines the ease of thermoplastic processing combined with the desirable physical properties of a thermoset. The connector is suitable as a replacement for copper tubes with associated fittings as well as polybutylene tubing.
