B&G Sprayer Parts & Accessories

Keep Your Sprayer in the Field with Genuine B&G Sprayer Parts

A worn gasket, a cracked hose, or a faulty pump valve can bring an entire treatment to a halt. For pest control operators, homeowners, and commercial applicators who depend on B&G sprayers, downtime is not an option. DIY Pest Control stocks a full inventory of B&G sprayer parts so you can diagnose the issue, order the correct component, and get back to work without delay.

B&G has been the professional standard in compressed-air sprayers for decades, and their equipment is built to last. But seals wear down, O-rings degrade from chemical exposure, and springs lose tension over time. Routine replacement of these wear items is what separates a sprayer that performs consistently from one that leaks, loses pressure, or delivers an uneven spray pattern. We carry genuine and compatible B&G replacement components for the full lineup of B&G sprayer models, including the popular 1-gallon and 2-gallon stainless steel units.

Common B&G Sprayer Parts and When to Replace Them

Knowing which B&G sprayer parts to keep on hand can save valuable time during a busy treatment schedule. These are the components that pest control professionals replace most often:

• Gasket Kits (GD-124): The seals inside a B&G sprayer are exposed to chemical solutions on every use. Over time, they swell, crack, or lose their ability to hold pressure. If your sprayer is losing air pressure faster than usual or leaking around the pump assembly, a gasket kit is typically the first fix. Replace gaskets at least once per season, or more frequently under heavy use.
• Hoses: The red hose on a B&G sprayer sees constant flexing, chemical contact, and UV exposure in the field. A brittle or cracked hose can leak or burst under pressure. B&G offers chemical-resistant hoses built to withstand repeated exposure to professional-grade pesticide solutions.
• Pump Units: If your sprayer is not building or holding pressure, and new gaskets do not solve the problem, the entire pump unit may need replacement. We stock pump assemblies for half-gallon, 1-gallon, and 2-gallon B&G models.
• Syphon Tubes: A cracked or corroded syphon tube affects how the solution is drawn from the tank. The B&G OS-792 stainless steel syphon tube resists chemical corrosion and is a direct replacement for the factory part.
• Tips and Nozzles: Spray tips control flow rate and pattern. Worn or clogged nozzles lead to inconsistent application and wasted product. Keeping a spare set on hand allows for quick swaps in the field.
• Wands and Valves: The VersaGun valve and various wand extensions allow technicians to reach tight spaces, apply crack-and-crevice treatments, and adjust spray patterns. If your valve is sticking, dripping, or not shutting off cleanly, a rebuild kit or replacement valve will restore precise control.
