They are made of brass, stainless steel, galvanized steel, and other materials that resist corrosion, pressure, and wear. Hose fittings have various types of connections, including threaded, barbed, push-to-connect, dry disconnect, and others including those based on internationally-accepted specifications.

Review: Good parts to have - Thank you it’s a big necessity
Review: 2 thumbs up - Does its job: check Not made in China: check Two thumbs up. Tefen nylon 66 hose barbs work nicely on 3/4" Swann garden hose. Their fit is tight enough I was glad to have a heat gun to soften the hose. The DIY clamps in my pic were made with ASINs B06Y1VYR9F and B00XWK7SNC. This review is not a compensated promo. I bought all these items.
