Hey there. Bought this in a 14mm/18mm and 18mm/14mm male to female adapters. Love them both and use all the time with my c2 customs water pipes, work fine on all three that I own. Glad to see USA made adapters. Good company and good product and glass. Both adapters are Strong and well made. Fast shipping. Thanks.
