Profile rings WR-15 acc. DIN 3869 are axial-static sealing rings made of elastomer used in threaded joints and tube fittings.
Advantages
- Very little leakage, even with thin liquids
- Strong resistance to gap extrusion
- Keeps its shape well, even under pressure
- Simple to install
- Does not twist inside the groove
Applications
Used as an axial static seal in threaded joints for: construction machines, machine tools, hydraulic presses, injection molding machines, agricultural machines, shipbuilding equipment, hydraulic valves, fittings.
Material NBR 85 black
NBR has good resistance to mineral oil-based oils and greases, aliphatic hydrocarbons, vegetable and animal oils and fats, hydraulic oils H, H-L, H-LP, hydraulic fluids HFA, HFB, HFC, silicone oils and silicone greases, water (max. 80°C).
NBR is not resistant to fuels with high aromatic content, aromatic hydrocarbons, chlorinated hydrocarbons, polar solvents, hydraulic fluid HFD, glycol-based brake fluids, ozone, weathering, ageing.
Application temperature range: -30°C to +100°C
Material FKM 80 green
FKM has good resistance to mineral oil-based oils and greases, synthetic oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, hydraulic fluids HFD, vegetable and animal oils and fats, silicone oils and silicone greases, fuels, non-polar solvents, ozone, weathering, ageing.
FKM is not resistant to glycol-based brake fluids, polar solvents (e.g. acetone), steam, hot water, amines, alkalis, low-molecular organic acids (e.g. acetic acid).
Application temperature range: -15 to +200°C
