Hot Tap Adapters

A hot tap water line is a pressurized water main that is tapped, or connected to, while it remains in service and under pressure. Using a tapping machine, adapter, and cutter, a new branch connection or valve is installed without shutting down flow, avoiding costly service interruptions for utilities and customers.

Schallert Enterprises manufactures tapping adapters ranging from 4 inches to 54 inches to fit any size tap and tapping machine. Lightweight aluminum adapters are available in 4 to 16 inch sizes, while standard adapters cover the full 4 to 54 inch range for larger pipeline tapping applications.

Standard adapters are built for general hot tapping use on any tapping machine, while lightweight aluminum adapters reduce overall weight for tight, indoor, or confined-space jobs where a forklift or crane cannot access the tapping machine. Both share the same ANSI 150# bolt pattern for compatibility.

All tapping adapters feature a standard ANSI 150# bolt pattern, ensuring compatibility with common pipeline fittings and valves. An optional double-drilled pattern is also available upon request to fit MJ (mechanical joint) valves, giving crews flexibility across different pipeline configurations without sourcing separate hardware.

Yes, tapping adapters can be double drilled to accommodate MJ (mechanical joint) valves in addition to the standard ANSI 150# bolt pattern. This custom drilling option is available upon request, allowing the same adapter design to be adapted for different valve and fitting configurations in the field.

Schallert Enterprises manufactures adapters for any size tap and every tapping machine, including its own TM100, TM200, and TM250 series. Lightweight aluminum adapters are specifically suited for use with TM200 and TM250 machines in tight or indoor tapping situations requiring reduced equipment weight.
