Crown Engineering 40450 Copper Oil Supply Line 3/16x5

Product Description

The CROWN ENGINEERING 40450 is a straight copper oil supply line measuring 3/16 inches in outer diameter and 5 inches in length. It is used to route fuel oil from a supply source to a burner or oil valve in heating equipment. Copper construction provides reliable resistance to corrosion and ensures a clean, leak-free fuel path when properly flared or fitted. This type of line is a standard service part installed by oil burner technicians and HVAC professionals during routine maintenance, burner replacement, or fuel system repair.

This straight copper oil line is suited for residential and light commercial oil-fired heating systems, including forced-air furnaces and boilers that use No. 2 fuel oil. Its compact 5-inch length makes it appropriate for short runs between components within a burner assembly or equipment cabinet. It is a direct replacement for worn, kinked, or damaged oil lines of the same size during service calls.

Key Features

• Straight configuration for simple, direct fuel routing
• 3/16-inch diameter matches common oil burner line fittings
• 5-inch length suits tight cabinet or burner assembly installations
• Copper construction resists corrosion and is compatible with No. 2 fuel oil
• OEM-style replacement simplifies like-for-like service

Compatibility

Designed as an OEM-style replacement copper oil supply line for oil-fired residential and light commercial heating equipment requiring a 3/16-inch diameter straight line.

Installation Notes

Installation should be performed by a qualified oil burner technician or licensed HVAC professional. Shut off the fuel supply valve and de-energize the burner before beginning any work on the oil line. Ensure all fittings are properly flared or compression-seated to prevent fuel leaks before restoring power and fuel flow. Follow all applicable local codes and NFPA 31 guidelines for oil-fired equipment service.
