Scope & Application


Intended for use in pressure piping systems for the conveyance of ultrapure water. IPS sizes 1/2" through 6", for use at ambient temperatures up to and including a maximum of 140°F. Pressure rating (160 psi to 420 psi) varies with pipe size, temperature, and component limitations as stated in GF Harvel® Plastics, Inc. LXT® product bulletin (HPB-114). Pipe exhibits excellent surface finish characteristics, good physical properties and exceptional low extractable qualities that reduce the potential for micro contamination in UPW applications.


This specification outlines minimum requirements for Harvel LXT® Schedule 80-iron pipe size (IPS) UPW pressure pipe. This piping system is intended for use in ambient temperature ultrapure water systems where the fluid conveyed does not exceed 140°F.
