Series 402 & 402-L stainless steel connectors combine 300 series corrugated stainless steel hose and braid with weld-on carbon steel flanges for a high-pressure assembly. 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 402 are made to traditional industry standard overall lengths. These connectors are designed to provide good efficiency for noise and vibration control. Series 402-L are longer length connectors, built for even greater noise and vibration control, and a minimum of 2” permanent lateral offset.
