Specifications

The 9/32" flowEFC12 Seriescouplings feature a highefficiency valve design that providesa greater flow capability than any othercoupling its size. Chemically resistant polypropylenematerial makes it ideal for harsh environments.The EFC12 Series adds a bulkhead panel mount option fortight seals against tank walls and drums.Actual sizeEFC12 SERIESSpecificationsPressure: Vacuum to 105 psi, 7.2 barTemperature:32°F to 160°F (0°C to 71°C)Materials:Main components and valves: PolypropyleneThumb latch: PolypropyleneValve spring: 316 stainless steelPanel mount gasket: EPDMExternal springs: 302 stainless steelO-rings: EPDMColor:Gray with dark gray latchTubing Sizes:1/4" and 3/8" ID, 6.4mm and 9.5mm IDFeaturesHigh efficiency valvePlastic thumb latchPolypropylene materialCompatibleBenefitsMore flow in a compact sizeFewer moving partsChemically resistant and gamma sterilizableMates with most APC couplingsEFC12 SERIESThese graphs are intended to give you a general idea of the performance capabilities of each product line. The shaded area of each graph representsthe operating range of the product family, i.e., upper and lower values are shown. Therefore, depending on the exact coupling configurationsselected, you can reasonably expect values to fall within the shaded area.Liquid Flow RatesLiquid Flow Rate Information for CouplingsThe chart below shows the flow rate for Colder couplings. Each coupling was tested with water at 70°F(21°C). To determine flow rates for specific coupling configurations use the formula below.C VValues for EFC12 CouplingsEFC EFCD EFC EFCD EFC EFCD EFC EFCD EFCD EFCDBODIES 22412 22412 22612 22612 23412 23412 23612 23612 24412 24612EFCD10412 0.51 0.51 0.51 0.51 0.50 0.45 0.50 0.50 0.51 0.51EFCD10612 0.61 0.51 1.13 0.72 0.50 0.45 0.81 0.69 0.51 0.72EFCD16412 0.51 0.51 0.51 0.51 0.50 0.45 0.50 0.50 0.51 0.51EFCD16612 0.61 0.51 1.13 0.72 0.50 0.45 0.81 0.69 0.51 0.72EFCD17412 0.51 0.51 0.51 0.51 0.50 0.45 0.50 0.50 0.51 0.51EFCD17612 0.61 0.51 1.13 0.72 0.50 0.45 0.81 0.69 0.51 0.72Q = Flow rate in gallons per minuteC V= Average coefficient across variousflow rates (see chart)P = Pressure drop across coupling (psi)S = Specific gravity of liquid48
