URETHANE BACK-UP RING KIT

THE URETHANE BACK-UP RING IS A LITTLE HARDER COMPOSITION THAN THE BUNA-N AND IS THE ONE WE PREFER TO USE IN OUR SHOP. IT IS ABOUT THE SAME HARDNESS AS THE TEFLON BUT HAS THE ADVANTAGE THAT IT WILL RETURN BACK TO SIZE AFTER STREATCHING WHERE AS THE TEFLON WILL NOT. THIS KIT CONTAINS 475 PIECES AND 24 OF THE MOST POPULAR SIZE BACK-UP RINGS. CLICK ON THE PICTURE BELOW FOR THE SIZES AND QUANITIES.
