The Hydra-Stop HSF 250 Patriot Line Stop fitting is a step forward in line stopping technology. The HSF 250 line stop fitting incorporates features that matter most to our customers — 250 psi working pressure, American Iron and Steel Act compliant, UL NSF 61 Classified, Heavy Duty Stainless Steel Construction and a Push and Pin Completion Plug system.


Device The HSF 250 Patriot water main line stop fittings are NSF 61 and ANSI 372 certified by Underwriters Laboratories, Inc. to be used as a fully UL® compliant component of water systems in the United States. (10" and 12" certification pending.)

NSF/ANSI Standard 61 was established to provide minimum requirements for the control of potential adverse human health effects from products that contact drinking water. This includes criteria for testing and evaluating products to ensure they do not leach potentially harmful contaminants into the water system.
