Sealed vacuum insulation and a reflective barrier inside this hose maintains the temperature of liquids as cold as -325° F. Similar to a thermos, this prevents heat transfer, so the exterior of the hose won’t freeze or form condensation. The tube stems on each end slide into tube fittings on a freezer or other equipment in your plant or laboratory.

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

This premium-grade tubing is polished to a 20 Ra or 15 Ra finish on the inside to reduce particle buildup and allow for easy cleaning.

Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.
