Part 0550066A is a male hose-to-hose coupling used to connect two high-pressure hoses or attach a hose to a sprayer outlet. Constructed from durable brass or steel, it features a threaded male end that seals securely with a female swivel connection. Replacing a worn or damaged coupling restores leak-free performance and helps maintain full operating pressure on compatible airless sprayers.
