5. FAQ
Q: What are the key properties of silicone rubber for these O-rings?
A: Silicone offers excellent heat resistance (operating range roughly -60°C to +200°C), great flexibility even at low temperatures, and strong resistance to ozone, weathering, and aging. It works well with hot air, steam, and non-polar fluids, though it is not recommended for use with most mineral oils or fuels.
Q: How do I install these O-rings correctly?
A: Start by thoroughly cleaning the O-ring groove and mating surfaces to remove all dirt, burrs, or old seal residue. Lightly lubricate the O-ring with a compatible fluid or grease to ease installation. Carefully fit the seal into the groove, making sure it does not twist, overstretch, or get pinched. When assembling components, avoid sharp edges that could damage the seal.
Q: What common mistakes cause these O-rings to fail early?
A: The most frequent causes are improper installation (twisting, pinching, or overstretching), chemical incompatibility with the system fluid, extreme temperatures leading to hardening or brittleness, scratches on mating surfaces, and using the wrong size or hardness (durometer) for the application.
