FS85 Rubber Plug: The "Port Sealing Guard" of Small Engines

The FS85 Rubber Plug is the "port sealing guard" for small engines like FS85, designed for leak prevention of equipment oil/water ports. Its main body is made of high-purity nitrile rubber, with a swelling rate of less than 2% against gasoline and engine oil—no material softening or seal failure after long-term fuel contact.

The reinforced seal layer on the plug surface is vulcanized, with an elastic recovery rate of 95%. It fits tightly to the port inner wall after installation, maintaining a sealed state even when the equipment vibrates; the tapered structure matches the port size of FS85 models, enabling easy plugging/unplugging and no easy falling off.

In outdoor operations, old plugs often have "oil leakage" due to aging and corrosion, which not only wastes consumables but also contaminates equipment and accelerates component wear. After replacing with the FS85 Rubber Plug, the port sealing level is upgraded to IP65, the leakage rate drops to 0, and the plug’s service life is extended to over 500 hours.

Whether for engine maintenance of garden tools or port sealing of small machinery, the FS85 Rubber Plug can guard the port sealing boundary of equipment with "oil resistance + tight seal + anti-aging" performance, being a basic sealing component for stable operation of small power equipment.
