THE ZAVA® QUICK-LOCK
Acid-proof steel (SS 2343, ASTM 316)
The steel grade EN 1.4436 is a stainless, acid resistant steel with improved machinability. Since the steel is machinability improved, it is suitable for production of details with comprehensive machining. The steel has very good corrosion resistance particulary in chloride-bearing environments and is extra resistant to pitting corrosion, crevice corrosion, stress corrosion cracking and corrosion fatigue. It also has high strength and toughness. It´s preferable in industrial environments.
The O-rings can be made in different materials
ALWAYS IN STOCK
ZAVA® 90-55 MODIFIED NBR
1/2″, 5/8″, 3/4″ and 1″ (13 mm, 16 mm, 20 mm och 25 mm)
Modified NBR is the Ideal for use as seals for pumps and other general engineering applications in the hydraulic and pneumatic industry. Modified NBR is good for applications where the O-ring is exposed to fats, greases and animal or vegetable oils. Lubricating oils, hydraulic fluids, pulp solutions with SO2, ClO2, NaOH, Na2S, CaO, Cl, H2O, NaCl, red liquor, brown stock and normal concentrations of most chemicals used in Pulp and Paper mills.
Do not use: with fireproof hydraulic fluids or concentrated acids
Recommended temperature range: -22°F to +230°F (-30°C to +110°C)
5/8″ and 3/4″ (16 mm and 20 mm)
Aflas® provide excellent chemical, high temperature, steam and caustic resistance up to 400° F (204° C). TFE/P rubber, Aflas® fluoropolymer materials provide dependable sealing performance in water, steam bases, and caustic environments resulting in their typical use in the oil exploration and drilling industry. It´s suitable for agressive bleaching agents, strong acids, bases, lubricants and highly reactive organic and inorganic chemicals. It´s also ozone resistant and radiation resistant up to 200 MRad of gamma-ray radiation.
Recommended temperature range: -13°F to + 400°F (-25°C to +204°C)
EPDM 70-compound 55914 is made of Ethylene-Propylene, standard cord industrial quality.Very good ozone and weathering resistance, as well as the resistance to acids and hydroxides with low concentration. Ethylene Propylene has gained wide seal industry acceptance for its excellent ozone and chemical resistance characteristics. O-rings manufactured from EPDM exhibit an excellent resistance to weathering and ozone, water and steam.
Not compatible with: Mineral oil products (oils, greases and fuels).
Recommended temperature range: – 67°F to +266°F (-55°C to +130°C)
FPM 70-compound 514308 have combining high temperature resistance with out- standing chemical resistance, Fluorocarbonbased compounds approach the ideal for a universal O-ring material. Resist mineral oils and greases, aliphatic, aromatic and also special chlorinated hydrocarbons, petrol, diesel fuels, silicone oils and greases. It is suitable for high vacuum applications. Many fluorocarbon compounds have a higher than normal mold shrinkage rate. FPM has found wide acceptance in the aircraft, automotive and chemical industries. Very good ozone, weather and aging resistance
The terms FPM, FKM and Viton® stand for one single base material: fluorocarbon rubber.
Recommended temperature range: -4°F to +392°F (-20°C to +200)
