HEWITT
Frequently asked questions
Common questions about HEWITT from 3G Electric.
What are the thread types and sizes available for HEWITT swivel connectors?
HEWITT swivel connectors are available with BSPF (British Standard Pipe Female) and BSPM (British Standard Pipe Male) threads. Common sizes include 1 1/4 in and 1 1/2 in. For example, SKU 912MR8 has a 1 1/2 in BSPF female inlet and 1 1/2 in BSPM male discharge, while SKU 912MR9 has a 1 1/4 in BSPF female inlet and 1 1/2 in BSPM male discharge. The specific thread type and size determine compatibility with existing hose or pipe connections. Always verify the required thread configuration for your application.
What fuels are HEWITT swivel connectors and strainers compatible with?
HEWITT swivel connectors with aluminum bodies are chemically compatible with kerosene, as indicated in the product specifications. The inline strainers are designed for fuel transfer pumps and are used to filter debris from fuel. For other fuels, such as diesel or gasoline, compatibility should be confirmed with the manufacturer or based on chemical resistance data. The aluminum body material may not be suitable for all fuel types, so always check compatibility before use.
How do I select the correct HEWITT inline strainer for my fuel transfer pump?
HEWITT inline strainers are compatible with specific manufacturer model numbers. For instance, SKU 912N83 is compatible with model number 1149812N, and SKU 912MT2 is compatible with model number 12090219N. To select the correct strainer, identify the model number of your fuel transfer pump and match it to the compatible HEWITT strainer. The strainers have aluminum bodies and are designed for inline installation to filter debris and protect pump components. If your pump model is not listed, consult the pump manufacturer or a HEWITT distributor for assistance.
What is the purpose of a swivel connector in a fuel-handling system?
A swivel connector, such as those in the HEWITT line, allows rotation between connected components, such as a hose and a pipe. This rotation helps reduce hose kinking and twisting during fuel transfer operations. The connector typically has a female inlet and male discharge (or vice versa) with threaded ends. HEWITT swivel connectors feature aluminum bodies and are available in various BSP thread sizes. They are used in fuel-handling systems to provide flexibility and prevent strain on hoses, which can extend hose life and improve safety.
Are HEWITT fuel transfer strainers compatible with biodiesel or ethanol blends?
The product specifications for HEWITT inline strainers indicate compatibility with fuel transfer pumps and aluminum body material. However, specific chemical compatibility with biodiesel or ethanol blends is not stated in the available information. Aluminum can be affected by certain biofuels, particularly those with high acid content or water contamination. For applications involving biodiesel or ethanol, it is recommended to verify compatibility with HEWITT or test the material under operating conditions. Always follow the fuel manufacturer's guidelines and consider alternative materials if necessary.
