Fischer & Plath Metal Seal Ring Washer Copper

Fischer & Plath copper metal seal rings (also called crush washers, sealing washers or gaskets) create a leak-free seal on drain plugs, banjo bolts and threaded fittings. Copper compresses under torque and conforms to the mating surfaces. This helps stop oil, fuel and coolant from seeping past the fitting.

Key Features:

• Compressible copper construction: deforms under clamping load to seal the fitting.
• Common uses: engine oil and transmission drain plugs, banjo bolts, and fuel, coolant and oil line fittings.
• Precision-stamped: made by Fischer & Plath, a European maker of machined seals, shims and precision stamped metal parts.
• Multiple sizes available: choose the inner diameter, outer diameter and thickness that match your fitting.

Installation note: crush washers are generally single-use. Once compressed, a washer will not reseal reliably, so replace it each time the plug or bolt is removed.

Fischer & Plath copper seal rings are an inexpensive way to prevent leaks between service intervals. Keep a few on hand for oil changes and fluid line service.
