1/4" Barb x 1/2" MPT Straight Fitting 316 Stainless Steel - S201-4D

The S201-4D is a commercial-grade straight adapter designed to securely bridge a flexible 1/4" ID hose directly to a 1/2" female NPT threaded connection. Machined from premium 316 stainless steel, this heavy-duty fitting provides superior resistance to chloride pitting, chemical stress, and heavy rust compared to standard 304 or 303 alloys.

This straight adapter is certified and fully passivated, making it ideal for the strict sanitation standards required in commercial brewing, beverage dispensing, draft wine installations, and food service environments. It is equally suited for harsh pneumatic air line networks, automotive setups, and marine plumbing. For optimal performance, secure the barb using high-tensile Oetiker or worm-gear hose clamps and wrap the male pipe thread in heavy-duty PTFE sealing tape during installation.
