Metallics 1220CTE – Frequently Asked Questions
1) What thread size is the Metallics 1220CTE tap plug?
The 1220CTE is a 1/2-20 tap plug, meaning a 1/2 inch diameter with 20 threads per inch. That is a fine thread pitch, so it will only seat in a hole tapped 1/2-20. A 1/2 inch hole cut with a coarser thread will not take it.
2) Will the 1220CTE thread into 1/2 inch conduit or a 1/2 inch knockout?
No. Trade size 1/2 inch conduit and conduit hubs use NPT or the standard conduit thread, not a 1/2-20 machine thread, and a 1/2 inch knockout is unthreaded. The 1220CTE is for a hole actually tapped 1/2-20. For a knockout or a conduit opening you need a knockout seal or a threaded conduit plug instead.
3) Is the Metallics 1220CTE tap plug steel or plastic?
Carbon steel. That gives you a threaded metal plug you can torque into a tapped hole without the crushing or cold-flow you get from a plastic plug, which is what most electrical and MRO buyers want when the plug is closing off a hole in a metal enclosure or housing.
4) How many tap plugs come in a Metallics 1220CTE order?
One piece per order, supplied in a pouch. If you are plugging multiple holes across a job or stocking a service van, order the quantity you need up front rather than assuming a multi-pack.
5) What is a tap plug like the 1220CTE actually used for?
It closes off a threaded opening. Electricians and maintenance crews use tap plugs to seal unused tapped holes in conduit bodies, fittings, boxes and enclosures so the opening is filled and the assembly stays closed up. The 1220CTE handles any 1/2-20 tapped hole.
6) Do I need a sealant or washer with the Metallics 1220CTE tap plug?
The 1220CTE ships as the plug alone, one piece in a pouch, with no gasket, washer or sealant included. If the application needs a liquid-tight or weather-resistant closure, plan on thread sealant or a sealing washer as a separate line item.
