Unisource Series 401 & 401-L stainless steel braided pump connectors are the standard of the industry for a rugged, versatile flex product to connect piping to vibrating mechanical equipment.
Series 401 & 401-L stainless steel connectors combine 300 series corrugated stainless steel hose and braid with weld-on carbon steel end fittings for a high-pressure assembly. Standard connectors with stainless steel end fittings are also available. Unisource starts with a high corr-count inner hose for greater flexibility and better noise and vibration control efficiency. Many manufacturers utilize a less expensive wide-pitch corrugated hose. A tightly woven stainless steel braid provides high pressure ratings, even in high temperature heating water applications. Series 401 threaded are made to traditional industry standard overall lengths. These connectors are designed to provide good efficiency for noise and vibration control. Series 401-L are longer length connectors, built for even greater noise and vibration control, and a minimum of 2” permanent lateral offset.
