Threadless Plugs

Learn About Threadless Plugs
DME's Threadless Plugs are made of brass to prevent corrosion. They are in both imperial and metric sizes to support your needs. At DME, threadless plugs are available in stock for quick delivery to keep your mold running. Our Threadless Plugs are designed to place inside water lines and are used to divert the flow of coolant in these lines.
Our Threadless Pressure Plugs employ a time-saving expandable O-ring design. As the plug’s socket head screw is tightened, the O-ring expands to provide a positive seal, eliminating the need for a thread. No tap holes are required, which makes installation quick and easy. The smaller diameters are ideal for use in cavity inserts or slide blocks where space is limited. (Not recommended for use in oil lines.)
These threadless plugs are brass threadless pressure plugs.
We charge between $3.33 and $24.98
