The R-410A BM Series manifold is specially designed to handle the higher working pressure of this refrigerant, says the company. Its features include an extra-large sight glass held in by a brass ring instead of a hardened rubber ring. The gauges for the low side go to 500 psi instead of 350 psi, and the high side goes to 800 psi instead of 500 psi. Hoses have a working pressure of 870 psi and a burst pressure of 3,480 psi. The manifold also comes standard with color-coded, dampened, and adjustable heavy-duty gauges.
