Hello,

I am looking to purchase Rubber O Ring Black NBR Rubber Gasket O Ring
I need :
1) 20 pcs. of square HNBR rings with size of 15.0 (ID) x 19.1 (OD) х 2.05 (H) mm, Hardness 70 Shore A
2) 20 pcs. of square HNBR rings with size of 17.0 (ID) x 21.1 (OD) х 2.05 (H) mm, Hardness 70 Shore A

I need it to be 2.05 mm precisely. So you've got to use a grinding (sharpening) manufacturing method, not molding.
That's to be a trial batch of rings.
Thanks
waiting for your response
