Features Medical grade material, safe and nontoxic.This one way check valve is convenient for replacing the broken one. Resistance to high temperature of 150 degrees, ozone resistance, and corrosion resistance. It has enough pressure bearing capacity and rigidity to meet the actual use requirement within its proper range. High mechanical strength, wear resistance and durability. Widely used in water treatment, air purification, automotive parts, machinery industry, medical equipment, household appliances and other fields Specification:Shell material: PPSealing material :VITON,SILICONE(Optional)Type(Optional):  PP shell/SILICONE Sealing material, PP shell/VITON Sealing materialSize:3/8" 10mmConnection form: quick installStructure: diaphragm one-way valveApplicable media: all kinds of highly corrosive chemical mediaForm: diaphragm typePressure environment: normal pressureStandard: British standardDirection of flow: one-wayWorking temperature: normal temperatureDiaphragm one-way valve opening pressure < 0.5kpa (0.005kg water pressure)Weight: Approx.3g/0.1oz Sealing materialFluorinated rubber (VITON) : with high temperature resistance, oil resistance and resistance to a variety of chemical corrosion characteristics, fluorinated rubber has a high degree of chemical stability, is the elastomer in the medium resistance of the best one. Fluorine rubber has excellent anti - aging and ozone resistance. Fluorine rubber has a high solubility to gas, but a low diffusion speed, so it has a low air permeabilitySilicone rubber(SILICONE): it has the characteristics that are difficult to be replaced by other similar materials: good adsorption performance, good thermal stability, stable chemical performance, high mechanical strength, etc. Package list:1 x Inline Check Valve Package List
