Features: _x000D_ Medical grade material, safe and nontoxic; _x000D_ Resistance to high temperature of 150 degrees, ozone resistance, and corrosion resistance _x000D_ High mechanical strength, wear resistance and durability _x000D_ It has enough pressure bearing capacity and rigidity to meet the actual use requirement within its proper range _x000D_ Widely used in water treatment, air purification, automotive parts, machinery industry, medical equipment, household appliances and other fields _x000D_ This one way check valve is convenient for replacing the broken one _x000D_ _x000D_ _x000D_ Specification: _x000D_ Shell material: PP _x000D_ Sealing material :VITON,SILICONE(Optional) _x000D_ Type(Optional): PP shell/SILICONE Sealing material, PP shell/VITON Sealing material _x000D_ Size:3/8" 10mm _x000D_ Connection form: quick install _x000D_ Structure: diaphragm one-way valve _x000D_ Applicable media: all kinds of highly corrosive chemical media _x000D_ Form: diaphragm type _x000D_ Pressure environment: normal pressure _x000D_ Standard: British standard _x000D_ Direction of flow: one-way _x000D_ Working temperature: normal temperature _x000D_ Diaphragm one-way valve opening pressure < 0.5kpa (0.005kg water pressure) _x000D_ Weight: Approx.3g/0.1oz _x000D_ _x000D_ Material of valve body: _x000D_ Polypropylene (PP) : a semi-crystalline material that is hard and has a higher melting point. PP material with low thermal deformation temperature (100), low transparency and gloss, low rigidity, but have stronger impact strength, impact strength of PP increased with the increase of ethylene content increased. PP vicat softening temperature is 150. Due to its high crystallinity, the material has excellent surface stiffness and scratch resistance. There is no environmental stress cracking of PP. _x000D_ _x000D_ Sealing material _x000D_ Fluorinated 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 permeability _x000D_ Silicone 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. _x000D_ _x000D_ Package list: _x000D_ 1 x Inline Check Valve
