PrimoFlex Pro LRT Black ID 7/16 х OD 5/8 tubing review

Feature examining of PrimoFlex Pro LRT Black ID 7/16 х OD 5/8 tubing

Comments: 2

Before writing a review I had to make my always half-completed setup look good. The worst thing is that my Tygon 3603 tubing got a bit yellowish after using it for a year and it did not come off.

After a bit of thinking, I decided to change Tygon to new PrimoFlex Pro LRT Black ID 7/16 х OD 5/8 tubing. It would be interesting to all of you to see how well it performed.

Tygon 3603 ID 1/2 x OD 3/4 — PrimoFlex Pro LRT Black ID 7/16 х OD 5/8 — Tygon 3603 ID 7/16 x OD 5/8
Tygon 3603 ID 1/2 x OD 3/4 — PrimoFlex Pro LRT Black ID 7/16 х OD 5/8 — Tygon 3603 ID 7/16 x OD 5/8

I also found a piece of a new Tygon 3603 ID 7/16 х OD 5/8 tubing and added it for comparison. I cut a 0.2m piece of each tubing and bent along the ruler.

The distance between axis is 0.1m:

Tygon 3603 ID 7/16 x OD 5/8 — 0.1m between axis
Tygon 3603 ID 7/16 x OD 5/8 — 0.1m between axis
PrimoFlex Pro LRT Black ID 7/16 х OD 5/8 — 0,1m between axis
PrimoFlex Pro LRT Black ID 7/16 х OD 5/8 — 0,1m between axis

If bend radius is less than 0.05m — Tygon kinks. Can′t say that new Tygon tubing will also kink at small bend radius, but my half a year old sample could not bent as good as PrimoFlex Pro LRT did. Moreover PrimoFlex Pro LRT can bend at even smaller radius without any kinks. This is due to stiffness of PrimoFlex Pro LRT tubing. Tygon is way softer.

On the other hand Tygon 3603 adds no problems in attaching it to Bitspower Fat Boy 1/2 barbs while I had to apply force to do the same with PrimoFlex Pro LRT tubing — it means no more tube changing without taking off the watrerblock as I usually did — You can surely damage the MOBO.

In total, I am satisfied with the new tubing — it don′t fade (at least for now), bends perfectly and no more heat carrier evaporation, like 11-12ml per day on a 2.5m long tubing, as I saw on gas-permeable Tygon 3603 tubes.
