Big Fan of Bykski

I bought these fittings to prepare for my first ever acrylic hard line loop and was pleasantly surprised all around. The design of them are similar to that of compression fittings for air lines so I felt pretty confident. However, I had no idea they would completely seal even if I did not have them perfectly straight! Very happy with the build and the color.

In the picture I have used Bykski white and red fittings including the 90 degree angles. Also when I purchased the white fittings, the kit came with several sticks of acrylic tubing from Bykski as well. Everything worked really well for me.

Love these fittings!

Great fittings, once tightened, they hold the tubing tighter than others, which is a plus, they also look clean which helps.

Also the sour patch candy in every order is a nice touch :)
