Description

When you’re transferring liquids around the farm—whether it’s water, liquid fertilizer, or chemical spray mix—keeping dust and debris out of your cam lock fittings is critical. This 3-inch poly dust cap locks securely onto male adapters, protecting your connections from contamination that can clog spray nozzles or damage pumps. It’s one of those small parts that saves you big headaches down the road.

What You’re Getting

Durable polypropylene construction that handles farm chemicals and UV exposure without cracking
Stainless steel locking arms that won’t rust or corrode, even in wet conditions
Quick-lock cam design that secures in a quarter turn—no threading or fumbling with caps
Perfect fit for 3-inch male cam lock adapters on tanks, pumps, and transfer equipment

Built for Real Farm Work

This cap fits standard 3-inch cam lock male adapters used on liquid fertilizer applicators, spray tanks, water transfer systems, and portable chemical tanks. Whether you’re running a self-propelled sprayer, pull-type applicator, or nurse tank setup, these caps keep your fittings clean and ready for the next job. They’re especially handy on equipment that sits outside between uses.

Made to Last

Farm environments are tough on plastic parts, but this polypropylene cap handles temperature swings, chemical exposure, and UV rays without getting brittle or discolored. The stainless steel cam arms stay smooth and functional, so you can lock and unlock the cap easily even after years of use.

Good to Know

Installation is simple—just align the cam arms with the slots on your male adapter and turn a quarter turn to lock. Keep a few extras on hand since caps have a way of walking off or getting misplaced around the farm. A quick rinse after chemical use keeps them working smoothly.
