The MEPCO Steam Trap Repair Guide lists the vast majority of every steam trap produced by any manufacturer over the last 110 years plus. If by some chance you don’t see what you are looking for listed just call the factory and we help you find what you need.

Our repair cartridges allow you to repair any steam trap in your system without the need to remove the existing trap. This saves you time and money. We can help even if the original trap manufacturer is no longer in business.

Using our simple and quick guide just look up the manufacturer, find the size and model number of your existing trap and follow that over to our replacement car-tridge. It is as easy as that.

All cartridges come individually boxed and with instructions.

Since 1903, MEPCO has manufacturing a complete line of steam heating special-ties including thermostatic traps, float and thermostatic traps, bucket traps, vacuum breakers, radiator valves and thermostatic radiator valves.
