Premium Copper Sealing Washers 30Mm Inner 36Mm Outer 2Mm Thick 4Pack Flat Ring Gaskets Solid As Rocks For Heavy Duty Machinery And M30 Screws Hella Reliable
✔️ Four pack copper seal rings sized 30mm inner 36mm outer 2mm thick (1.18 x 1.42 x 0.08 in)
This set of heavy duty copper washer inserts provides a sturdy metal interface between fasteners and equipment housings, working as a handy solution for leaky sump drains, pump flanges, and automotive oil pans where rigid steel bolts require a yielding cushion to hold pressure.
✅ Pack contains four copper seal rings sized thirty millimeters inside by thirty six millimeters outside (one point one eight inches by one point four two inches)✅ Flat plate construction sits perfectly under fastener heads to stop fluid leaks across steel or aluminum joints
✅ Two millimeter gauge thickness handles repeated torque cycles without splitting or losing sealing pressure (zero point zero eight inches thick)
✅ Raw metal composition blocks corrosion buildup so the unit stays functional through years of rough shop use
💡 Why choose copper sealing washers for high vibration machinery repair?
The ductile metal core compensates for microscopic bolt movement while maintaining tight contact pressure across uneven mounting surfaces.
- Tighten standard hex bolts down easily since the soft alloy yields gracefully without chewing up mating threads
- Run hot engine blocks or hydraulic pumps confidently knowing the base material conducts thermal spikes away safely
- Swap worn factory seals in minutes thanks to exact dimensional tolerances that drop right into existing bolt holes
- Grab extra rounds for cheap garage maintenance on diesel engines and conveyor drives before catastrophic failures strike
