I'm looking for a stainless-steel hex pipe or sleeve that can fit over a 1/2 inch hex shaft. Could you please provide me with details about your available options? Additionally, I'd appreciate information on sizes, prices, and any minimum order requirements. If you have any specifications, such as wall thickness or length options, please include that as well. Thank you!
