Brasscraft SWB00-18N Water Heater Connector 3/4 Fnpt 18in Ss

Product Description

The BRASSCRAFT SWB00-18N is a stainless steel flexible water heater connector designed to supply hot or cold water to residential and light commercial water heaters. Built to a 3/4 inch nominal size with female NPT (FNPT) end connections on both ends, this connector spans 18 inches in length and is rated for 125 psi working pressure. The corrugated stainless steel construction provides flexibility for tight or offset installations where rigid pipe connections are not practical. Licensed plumbers and experienced DIYers rely on this type of connector for straightforward water heater hookups.

This connector is suited for residential water heater installations, including tank-style gas and electric units. The 18 inch length accommodates standard rough-in conditions where the supply stub-out and heater inlet are in close proximity. The FNPT fittings thread directly onto the water heater inlet and outlet ports as well as standard shutoff valve outlets. Its stainless steel construction resists corrosion in utility room environments where moisture and humidity are common.

Key Features

• 3/4 inch nominal FNPT connections on both ends for direct thread-on installation
• 18 inch length suits standard residential water heater rough-in spacing
• 125 psi working pressure rating handles typical residential supply line pressure
• Corrugated stainless steel body provides flexibility and corrosion resistance
• Domestic construction

Compatibility

Designed as an OEM-style replacement or new-installation connector for residential tank-style water heaters with 3/4 inch FNPT inlet and outlet ports.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the cold water supply and drain pressure from the lines before disconnecting any existing connectors. Apply thread sealant tape or compound to all NPT connections and tighten to hand-tight plus the appropriate number of turns per the fitting manufacturer guidance — do not over-torque stainless corrugated connectors. Inspect for leaks at both fittings after restoring water pressure.
