PrimoFlex™ Advanced LRT™ Tubing has been designed, formulated, and manufactured for today’s evolving standards in the PC water cooling industry. Advanced LRT™ has been carefully formulated to perform in a wide range of closed loop cooling systems, creating the most compatible water cooling tubing ever created.

PrimoChill’s proprietary blend of notably low durometer PVC and more rigid polymer resin provides PrimoFlex™ Advanced LRT™ with an unbeatable bend ratio and durability. PrimoFlex™ has been tested in exacting laboratory set-ups. This included tests with abrupt small radius bends and multiple directional changes. Advanced LRT™ tubing resisted both twisting and collapse in test results. This allows for tighter bends eliminating kinking that can cause cooling failures and reduction in system performance.

Smooth inner walls improve closed loop sanitation. Advanced LRT™ smooth surface inhibits particulate gathering or entrapment onto the tubing wall. This reduces the potential of bacterial growth and contamination. With this technology, Advanced LRT™ will keep your system looking and feeling as clean as the day it was installed..

  • This tubing is designed to work with 7/16in. x 5/8in. compression fittings or 1/2in. Barb w/ 11/16in compatible clamp. Lamptron, Bitspower, and other exact sized 5/8in clamps will not work with this size tubing!!

Note: Due to a lack of tolerances in fitting design, we have seen some minor issues when using LRT tubing along with strict size brands such as Bitspower.

  • Sold in two foot sections (an order quantity of 3 would result in three 2 foot pieces)

With the use of different components, materials, fluids, and flow rates, results may vary with the appearance of your tubing. Although Advanced LRT™ is designed to work with a large variety of cooling components the use of alcohols, Ethylene Glycol and as well as any other harmful chemicals is strictly prohibited and will void your warranty. Tubing will stain if “dyed” coolants are used. PrimoChill is not responsible for any damage caused by or when using this product.

If your fittings seem extremely tight when using our tubing there are some methods to navigate around this issue. One method is to dip the end of our tubing into very hot (not quite boiling) water prior to installation. This will make the tubing more pliable allowing tight compression rings to be mounted easier. Using this method will also create a seal between the tubing and fitting once the tube cools creating an added layer of security.

PrimoChill is not responsible for any hardware damage. Use at your own risk.
