Made in USA. This Pure Stealth #12 Female O-ring x #10 Reduced Barrier 90 Degree Hose End Fitting is compatible only with reduced barrier refrigerant hose. Reduced barrier refrigerant hose is smaller in diameter and significantly more flexible than standard barrier hose. The smaller size makes it easier to route and hide. Reduced barrier crimping dies are required for crimping. Use this fitting to connect #10 reduced barrier hose to the #12 O-ring connection on OEM GM receiver driers
