Features
- MIFAB® MR-500, M1-500 & M2-500 Series pressure drop activated brass trap seal primer, with inlet opening of 1/2 inch MNPT and outlet opening of 1/2 inch FNPT. Complete with four view holes and removable filter screen. Requires no adjustments and no air pre-charge. MIFAB's series of pressure activated trap seal primers (MR-500, M1-500 and M2-500) can be connected to any cold water line and will be automatically activated when a valve or faucet, that is on the line, is opened. A pressure drop of 3 psi will activate all of the trap seal primers. MIFAB's series of trap seal primers can be disassembled in the field. Their unique design permits filter replacement without affecting the performance of the primer. The o-ring seals are tested for reliability at a temperature range of -40 to 450 Deg F. The M-500 series of trap seal primers do not require adjustment. The operating range for all of MIFAB's series of trap seal primers is 20 - 80 psi.
