High flow rate, durability and quality are all of great concern.Supertech understands that each motor is unique in its requirement and demands. There fore Supertech offers valves in a range of materials to suit any motor.
* Stainless - Made as a one piece forged valve for higher strength and reliability. Supertech uses mostly EV8 (21-4N) for Intake and Exhaust Valves, however there are other alloys that are used with different heat treatments to manufacture Valves for specific applications.
To address the issue of high heat, Supertech uses two different types of coatings:
Chrome Coating - Widely used in performance valves
Black Nitride - This is a hardening treatment that provides a smooth surface then chromed valves and produces less friction between stem and guide.
* Inconel 751 - Nickel Base Alloy - Nickel base alloy is used for exhaust valves that reach very high temperatures, such as those in turbo or supercharged applications.
Supertech Valves are sold *Per Valve*. For Example, when order for a Model that requires 16 Valves, order Quantity: 16

Goes on easy, never melts, peels off easy
Size: 10MM 2ROLLS, Size: 10MM 2ROLLS
This stuff is a life saver! It was so awkward before I found this tape, id try bending the pins to hold it in place, I got so desperate one time I used painters tape lol what a mess.
This tape is great, it doesn't always look ptlretty when i apply it, but it always holds, never melts, and peels off so easily when I'm done. I'll definitely be buying more of this. I bought two rolls a about a month ago and I've still got 1.5 rolls left, and I use it like its going out of style

Really good product
Size: 10MM 2ROLLS, Size: 10MM 2ROLLS
I use this thermal tape when heat pressing designs onto shirts, and it’s been really useful for keeping the design in place while moving the shirt on and off the press. Without tape, the design can shift pretty easily, but this helps hold everything steady so the placement stays accurate.
One thing I really like is that it removes cleanly and doesn’t leave any sticky residue on the shirt or the design, which is important when working with heat transfer materials. It also holds well during the pressing process as long as it’s applied correctly.
The only small issue I noticed is that if you don’t press the tape down firmly when placing it, it can peel off a bit easier than expected. Making sure it’s stuck down properly fixes that problem though.
Overall, it’s a helpful tool for anyone doing heat press or shirt printing, especially if you want to keep designs from moving during the process.
