The only tool for the job

Used this to finish my acrylic tubes to length. It’s simultaneously perfect for fine-tuning length and also for removing 4” of extra tubing easily (as opposed to using a saw)

One leaked

I had to lower the rating to 4/5 because one of the five i got leaked and it would not be worth returning due to shipping and restock fees the others are working with no problems hopefully that one was just a fluke.


Looks so good and clean, zero leaks.
If you need additional offset distance, get the supported offset fitting.

Quick and Efficient

The bit made the job at hand so much quicker to get the burrs and hard edge off the tubing. Once you get the feel of it (take a spare piece of tube and practice) you can grind down to get a very precise length. Would recommend.

Good pump.

I have never had a problem with any Laing D5 so far(1). I have had several Laing pumps and one of this specific model. It is quiet, has adequate(2) output, and the PWM mode works well. While NOT inexpensive, I have several Laing D5 pumps that are over 10 years old still going strong.

(1) I have had Laing DDC pumps fail. I do not recommend DDC pumps.

(2) The output of this pump is adequate but could certainly be better. I am getting a second one to be sure that I get adequate flow.

PrimoChill Hardline/Rigid Watercooling Tubing Finishing Bit (RFB) - Ream/Deburr/Trim

Good little water temp display

Easy install, feels and looks well made. Display, although small is nicely clear. Would have preferred the power cable be something other than molex connection though. I went with the POM instead of acrylic to add some durability to my water block versus using the stock acrylic connection or the acrylic temp monitor version.


The straight fittings are great no issues, but the rotary 90's can leak at the joints

PrimoChill Fan / Panel Mount Rivet - 4 Pack

Excellent fittings

Primochills fittings just top tier! Suuuper durable coating, high quality chrome plating on the inside. I will always use fittings with sleeves instead of o rings.

Great pump reservior combo

I have two DV pumps in my case moving over a gallon of coolant through four 480mm radiators, a gpu and a cpu. Pumps silently move liquid through my entire loop to keep things chilled.

Perfect for radiators !

This is the absolute PERFECT fitting for a radiator with lian-li sl120 fans. It allowed me to put a 90 fitting and perfectly clear my radiator with the hose tightly and cleanly hugging the fans without touching. I would suggest putting these and a 90 off of every radiator port

Can't give this product a 5 star unfortunately (read the review)

The fit and finish of these 90 degree fittings are top quality, none of my fittings leaked, they do every single thing you would need from a 90 fitting. HOWEVER. i simply cannot give this product a 5 star. why on earth would you need to buy the 90 fitting AND a straight fitting aswell? There should be an option for G1/4' Threaded 90 to male barbed fitting. no straight fitting needed. This adds another spot that has a chance of leaking because of failed O-Rings. And at 15$ a fitting these are the best, but when you need to buy another 10 dollar fitting its now a 25$ fitting, and in the watercooling world you end up needing mostly 90's if im being honest. nearly doubling my cost of fittings. and for that and that alone i cannot give it a 5 star rating. there are other companies offering solutions that fix this very problem. 1 90 fitting, no straight needed.

Works well, but overpriced.

They work good even with nothing more than a single gasket, but many of the matte black ones were chipped that I received, and the coating thickness varied on each one, some were harder to slide over the tubing than others. Other brands include a compression ring as well to ensure no pull out, these do not.

Works great

Works great as an accent color wrapping the fuel lines on my motorcycle.


I haven't used them yet but the fittings looks cool. It will look better after I complete the build and add a black light

Distro Plate gets a 4 star, pump gets a 2-3 star...

Distro plate looks good, lights work, and holes are almost perfectly lined up, mine were about a 5mm too high, so it made my lines look slightly off, which is not a huge issue, just something to note. The pump its came with however is as near to garbage as you can get. It is noisy, and cannot be powered past 65% without making a grinding noise, and I assumed this was air early on, but it never got better. I have also tried numerous times to contact the company about getting the sizing for the pump so I can potentially upgrade it, but no reply. Since im stuck with it, its limited my 13900K's OC.

Hi Ben,
Thanks for the review! There doesn't seem to be any record of you contacting us or Bykski.US about the pump. We'll be happy to help if you reach out to
