The quality of the part is satisfactory. However, the product description is wrong. The dimensions show that it is a 1 inch inner diameter but as the name suggests the inner diameter is 32mm. I can't comment on how well this part works as it would require 1.25" to crimp into a 1" diameter hole. I think with Revain you pay money and roll the dice, just in case the groove is about 2mm wide.
