Is the OLS CAMLOCK A gravity connector, aluminum suitable for gravity unloading of tankers with operating pressure limited to 1 bar while rated for 6 bar operation?

Yes. The OLS CAMLOCK A gravity connector, aluminum is specifically designed for gravity unloading of tankers and the product description explicitly states: "Designed for gravity unloading of tankers (operating pressure should not exceed 1 bar)." Although the connectorâs maximum rated operating pressure is 6 bar, that higher rating does not override the application-specific restriction for gravity unloading. For gravity unloading of tankers you must keep the system pressure â¤1 bar as stated. Materials and sealing (aluminum body, NBR seal) and compatible media (gasoline, diesel, ULSD, crude oil, E20, E100, B20, B100) are suitable for the listed fluids, but do not exceed the 1 bar operating pressure for gravity unloading.

Can the OLS CAMLOCK A gravity connector, aluminum be used with ethanol blends like E20 and E100 without seal or material degradation?

Yes. The OLS CAMLOCK A gravity connector, aluminum is specified for use with gasoline, diesel, ULSD, crude oil, E20 (20% ethanol), and E100 (100% ethanol), as well as B20 and B100. Its listed sealing material is NBR and the connector material is aluminum. NBR has limited compatibility with high ethanol concentrations over long term, but the manufacturerâs specification explicitly includes E20 and E100, so it is approved for those blends per the product data. Ensure you operate within the stated conditions (gravity unloading, operating pressure not to exceed 1 bar for gravity use; general operating pressure listed as 6 bar) and follow manufacturer guidance for inspection and replacement intervals to avoid seal degradation.

Does the OLS CAMLOCK A gravity connector, aluminum require different seals for biodiesel (B20/B100) compatibility?

No. the OLS CAMLOCK A gravity connector, aluminum as described uses NBR (nitrile) seals and is explicitly listed as compatible with B20 and B100 in the product media list. Therefore no different seals are required for biodiesel (B20/B100) use according to that description. Note: NBR is commonly used for many hydrocarbon fuels and lower-concentration biodiesel blends; for prolonged exposure to highâconcentration biodiesel (B100) some users prefer FKM (Viton) or other biodiesel-resistant elastomers for improved long-term chemical resistance and swelling performance. If your application involves extended static contact, high temperatures, or critical long-term service, consider consulting the manufacturer or choosing a connector with a biodiesel-specific seal material.
