Features Stable: A professionally manufactured one-way water stop valve, suitable for all kinds of strong corrosive chemical media, with pressure bearing capacity and rigidity. Pressure: The opening pressure of the diaphragm check valve is less than 0.5kpa (0.005kg water pressure), which meets the actual use requirements. Suitable for: Widely used in water treatment, air purification, auto parts, machinery industry, medical equipment, household appliances and other fields. Use: Diaphragm check valve structure, easy to quickly replace damaged check valve, easy to install and simple to operate. Resistance: high mechanical strength, wear resistance and durability, high temperature resistance of 150 degrees, ozone resistance, corrosion resistance, the valve is suitable for various environments. Specification: Shell material: PP Sealing material :VITON,SILICONE(Optional) Size:3/8" 10mm Connection form: quick install Structure: diaphragm one-way valve Form: diaphragm type Pressure environment: normal pressure Standard: British standard Working temperature: normal temperature Diaphragm one-way valve opening pressure < 0.5kpa (0.005kg water pressure) Weight: Approx.3g/0.1oz   Material of valve body: 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.   Sealing material 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 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.   Package list: 1 x Inline Check Valve Package List
