Nu-Calgon EcoPure Charging Assembly (4175-10) for charging R-290 (propane) and R-600a (isobutane) systems with EcoPure refrigerant canisters. Heavy-duty charging hose with hand shut-off valve and an integrated magnet that holds the inverted canister on a gram scale, so small hydrocarbon charges can be weighed in to gram accuracy without a manifold gauge set. Charges to the low side only. Use with any scale that reads in grams; refrigerant (4175-20 R-290, 4175-30 R-600a) sold separately.
