It’s compatible with HPS 150, 250, and 350 Series fittings, so you know it’ll fit right in with your existing setup.
Now, let’s talk specifics. This is an AN-3 size coupler with a 90-degree angle, perfect for connecting two male 37-degree AN flared fittings. It’s compact, making it ideal for those tight spots where traditional hoses just won’t cut it. You can use it with push-on, nylon braided rubber, or even Teflon-lined hoses—whatever your project calls for.
