About Kelch

Since 1956, Kelch — a division of Bemis Manufacturing Company — has built a reputation as a go-to source for high-quality fluid and air management products. Headquartered in Sheboygan Falls, Wisconsin, the brand has spent decades engineering solutions that help operators contain, measure, and regulate fuel and other fluids across a remarkably wide range of equipment: from snowmobiles and ATVs to lawn tractors, construction machinery, and marine vessels.

At the core of Kelch's product philosophy is a commitment to precision and compliance. Their proprietary Click-To-Seal™ ratchet cap technology is a prime example — a patented design that delivers a positive, audible seal so users never risk overtightening, while simultaneously meeting EPA and CARB emissions standards. It's the kind of thoughtful engineering detail that separates a purpose-built cap from a generic replacement.

What Kelch Makes

Kelch's catalog spans fuel caps with integrated gauges, locking caps, vented and non-vented caps, dipsticks, reservoir tanks, roll-over vents, and Diesel Exhaust Fluid (DEF) caps for both on-road and off-road vehicles. Whether you need a direct OEM replacement for a John Deere diesel tractor, a snowmobile gas cap for a vintage Arctic Cat, or a heavy-duty auxiliary tank cap for construction equipment, Kelch likely manufactures a compatible solution.

The brand's integrated fuel gauge caps are a standout product line — instead of requiring a separate gauge or dipstick, these caps incorporate a visual fuel level indicator directly into the cap itself. This is especially valuable on equipment like ride-on mowers, snowmobiles, and ATVs where a quick-glance fuel check can save time and prevent mid-task shutdowns.

Why Choose Kelch?

Kelch products aren't just replacements — they're often upgrades. The brand frequently introduces updated cap designs that improve on older OEM specifications, offering better sealing, easier reading, and longer service life. For anyone maintaining aging equipment where original caps are discontinued or hard to find, Kelch's broad cross-reference catalog makes them an essential resource. Their fuel tank caps in particular are well-regarded for their durable construction and accurate integrated gauges, earning strong reviews from powersports enthusiasts and equipment professionals alike.
