Kelvindale Products , Australia's largest manufacturer of caps and plugs, now have colour coded grease caps available.
Kelvindale grease caps snap on securely over grease nipples to prolong the life of the part by helping to eliminate dirt, grit and moisture from getting in.
Manufactured from a low density polyethylene, these grease caps keep fittings clean and do not need to be wiped before every grease job. To keep them attached to their fitting, these grease caps feature an integral retaining ring
Also able to be used to mask and and protect fittings during painting, spraying, and transit, grease caps have numerous advantages. The various colour coding options; red, yellow, blue, green, black, and white, can indicate frequency or the type of lubrication.
