Threaded Joints and Tube Fittings
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°CMaterial 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).
