Freelin-Wade’s 85A multi-bore tubing is made with our proprietary Fre-Thane® polyurethane material, which provides superior flexibility with high abrasion and kink resistance. Best of all, our Fre-Thane® multi-bore tubing exhibits exceptional “memory”—it can be stretched and flexed to extremes, and will always return to its original shape.

What is Multi-Bore Tubing?

“Multi-bore tubing” is tubing with two or more tubes, or bores, that are extruded together in a single piece; Freelin-Wade offers twin, triple, and quadruple tube multi-bore tubing. Our 85A multi-bore tubing is produced as a single extrusion, which provides a sturdier bond between the bores than multi-color ribbon (MCR) tubing. However, this process requires that all bores be produced in a single color.

Ether-Based vs. Ester-Based Polyurethane Tubing

There are two basic types of polyurethane: ester-based and ether-based. Chemically, the two variations are very similar, with the only significant difference being the polyol alcohols used in their formulation. Ester-based polyurethane is less expensive than ether-based; however, it degrades far faster when exposed to moisture. Because of this, Freelin-Wade uses only ether-based polyurethane in the production of our Fre-Thane® multi-bore tubing.
