MIFABiÂ¿Â½ MR-500, M1-500 & M2-500 Series pressure drop activated brass trap seal primer, with inlet opening of 1/2" male N.P.T. and outlet opening of female 1/2" N.PT. 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 three p.s.i. 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 degrees to 450 degrees 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 to 125 p.s.i. All three models are listed with I.A.P.M.O. and C.S.A. and are tested and certified to the A.S.S.E. Standard 1018 and are so marked. U.S. Patent # 6,152,164

The MI-TEMP holds a selected water temperature to within one degree from any constant hot water supply regardless of pressure changes in the supply lines. It ensures a blend of mixed hot and cold water at the shower head and is fully automatic - only one moving part will equalize the hot and cold supply line pressures. As supply line pressures fluctuate, the brass piston will move enough to compensate for the change in pressure and release water only at the preselected temperature.
