Bull Plugs

A solid plug, and the isolation of fluids, is critical to the success of a piping system. Keddco’s commitment to quality ensures our end users can rely on the performance of our bull plug pipe fittings. Using Computer Numerical Control (CNC) precision machining, we manufacture superior performance bull plugs with a threaded nipple on one end and a securely closed end on the other.

Keddco services various industries requiring unique and custom pipe connectors. A bull plug is a necessary component as part of a means to drain a line during maintenance operations. We value and understand the importance of bull plugs to securely ensure the success of dead-ending a line, blocking further development. Knowing this, our skilled manufacturers guarantee precision quality and testing of our bull plugs for a reliable product our end users can depend on.


All of Keddco’s bull plugs are manufactured in accordance with MSS-SP-95, from A-106 Grade B seamless pipe and A-1000 series, low to medium carbon, fine grain, and bar stock. Just like our swages, Keddco’s bull plugs meet the requirements set out by The Association of Materials Protection and Performance ((AMPP), formerly known as NACE)) for sour service
