Scully overfill prevention products
The Scully line covers Intellitrol 2, ST-35 and ST-15 overfill controllers, optic and thermistor liquid level sensors, plug and cable assemblies with junction boxes, pull-away and break-away cables, sockets, rack and truck testers, and the ST-47 Groundhog ground proving controller. On a loading rack, the green plug is the thermistor connection, and the J-slot pattern on the plug has to match the socket on the truck.
Ordering Scully parts: what we need
Send the Scully part number from the cable tag or plug body, the sensor type (thermistor or optic), the number of J-slots and contacts, the cable length and whether it is straight or coiled, and the controller model it connects to. Photos of the plug face and the junction box help us confirm the assembly for sites in the GCC.

FAQ
Questions about Scully
Common questions about Scully equipment, part numbers and supply to Oman and the GCC.
01How do I identify the right Scully plug and cable assembly?
Look for the Scully part number on the cable tag or molded into the plug, then note the plug color, the number of J-slots on the plug body and the number of contact pins. Record the cable length and type as well. A plug with a different slot pattern will not lock into the truck socket, so these details must match the installed equipment.
02What is the difference between Scully thermistor and optic connections?
They serve two different sensor technologies. Thermistor sensors and optic sensors use different signals, so the rack controller, the plug and the truck socket must all be of the same type. Scully supplies sensors, plugs and sockets for both, and controllers such as Intellitrol 2. Tell us which sensor type your trucks carry before ordering a replacement cable.
03What is a Scully thermistor plug and cable assembly?
It connects the tank truck's thermistor overfill sensors to the loading rack monitor. If any sensor is wet or the circuit fails, the monitor stops the loading permit.
04Is Seven Star LLC a distributor of Scully?
No. Seven Star LLC is an independent industrial supplier in Muscat and is not a distributor or agent of Scully. We source Scully overfill prevention parts through commercial channels, check the model or order code against the manufacturer's documentation, and provide the manufacturer's datasheet and the certificates the manufacturer issues with the order on request.
05What should I send for a quotation on Scully loading-rack parts?
Send the Scully part number, a photo of the plug face and cable tag, the sensor type, the J-slot and pin count, the cable length, and the model of the rack controller. For controllers, add the supply voltage and the nameplate details. With this we can check the item against Scully documentation before quoting.
