Tapping Adapters

Standard steel tapping adapters are available from 4 inches to 54 inches in diameter, covering nearly every pipeline size. Lightweight aluminum versions are offered from 4 inches to 16 inches for smaller taps where reduced weight and easier handling are priorities.

Standard adapters are built from heavier-duty materials suited for use with cranes or forklifts, while lightweight aluminum adapters reduce overall weight for easier manual handling. Aluminum versions are ideal for tight or indoor tapping situations where heavy lifting equipment cannot be positioned.

Tapping adapters are manufactured with a standard ANSI 150# bolt pattern, ensuring compatibility with common flanges and tapping machines. For projects requiring compatibility with mechanical joint (MJ) valves, adapters can be double drilled to accommodate both bolt patterns on the same flange.

Yes, both standard and lightweight aluminum tapping adapters can be double drilled upon request to fit MJ valve bolt patterns in addition to the standard ANSI 150# pattern. This allows a single adapter to work across multiple valve configurations without needing separate parts.

Complete add-on kits, such as the TM100 6-inch kit, are rated for pressures up to 350 psi, making them suitable for most municipal and industrial pressurized pipeline applications. Pressure ratings can vary by adapter size and configuration, so specifications should be confirmed for each project.

Tapping adapters are manufactured to fit any size tap and are compatible with virtually every tapping machine, including TM100, TM200, and TM250 models. Custom manufacturing is also available to match adapters to specific tapping machines not covered by standard sizing.
