The 434-696 Quick Disc Nipple is a precision‑machined fitting that serves as the male connection point for quick‑disconnect couplers on Hydra M2000, Hydra M4000, and Hydra Pro Super airless sprayers. When paired with a matching quick disc coupler (such as 434-695), it enables rapid tool‑free attachment and detachment of spray guns, hoses, and accessories.
Over time, nipples can wear, develop burrs, or become damaged, leading to difficult connections, leaks, or unsafe locking. Replacing a worn nipple with this genuine Hydra part restores secure, leak‑free connections and ensures the quick‑disc system functions as intended.
