Due to supply chain issues brass couplings may be imported. If you require domestic couplings please call to place your order. There will be a surcharge and lead time is unknown. There is no change to the hose itself, which is woven and manufactured in the USA. We will switch back to U.S. manufactured couplings as soon as we are able.

Lead time for discounted direct-from-factory 10-pack average 3 to 4 months. See single hose SKU if faster shipping required.

Our 2 1/2 inch Made in USA double jacket firefighting hose meets and exceeds all NFPA 1961 standards.
