Key Features

• Genuine OEM Sealing Integrity — Manufactured to the original specification, this cap provides a consistent, oil-tight closure that prevents contamination and leakage at the filler port.
• Direct-Fit Replacement — Threaded to match the original filler neck dimensions across all compatible models; installs in seconds with no modification to the housing or cap bore.
• Broad Cross-Series Compatibility — A single part number covers CT trowels, BFS floor saws, GP and GV generators, PT and PDT pumps, VP, WP, BPU, and BPS vibratory plates, AP battery plates, and RD tandem rollers.
• Contamination Prevention — A correctly seated oil filler cap keeps dirt, debris, and moisture out of the crankcase or gear housing, protecting internal engine and drive components from accelerated wear.
• Fuel and Fluid System Safety — A cracked or missing filler cap can allow oil vapor and splash to contact hot engine surfaces, creating a fire hazard; replacing a worn cap promptly eliminates that risk.

The oil filler cap seals the engine or gearbox oil fill port, keeping the lubricant inside the housing and contaminants out. When the cap is intact and seated correctly, it maintains the closed crankcase environment that modern small engines rely on for consistent lubrication and pressure balance. A damaged, missing, or poorly fitting cap allows dirt and moisture to enter the oil supply, accelerating internal wear, and can also permit oil to splash onto hot surfaces during operation — a condition that shortens component life and introduces a burn or fire risk. Replacing a worn or lost cap with the correct OEM part is one of the simplest and most cost-effective preventive maintenance steps available.
