Hello,
Do you have any experience with the PTFE coated aluminium alloy as housing for sealing. Coating like Xylan, Teflon on PTFE anodizing.

I would like to use simerings for sealing shafts diameter from 6 to 12 mm, 400-800rpm O rings as static sealing. EPDM for epoxy resin NBR for grease. Low pressure of resin, 1,5bar maximum.

Thanks
