Pump O-Ring Seal for Solo 425 and 475 Backpack Sprayers

Description

When your backpack sprayer starts losing pressure or you notice chemicals leaking around the pump, it’s usually a worn o-ring that’s causing the trouble. This little rubber seal might be small, but it’s what keeps your pump working properly and prevents nasty chemicals from dripping where they shouldn’t. Getting the right replacement means you can get back to spraying fence lines and treating problem areas without the hassle.

What You’re Getting

• Precision-fit seal designed specifically for Solo 425 and 475 pump assemblies
• Chemical-resistant rubber that stands up to herbicides, pesticides, and fertilizer solutions
• Reliable seal that maintains consistent pressure for even spray patterns
• Direct replacement part that installs just like the original

Built for Real Farm Work

This o-ring fits the popular Solo 425 and 475 backpack sprayers that you’ll find on farms and ranches across the country. Whether you’re spot-treating weeds along fence rows, applying herbicides around buildings, or handling larger spray jobs around the property, these sprayers are workhorses that need reliable seals to keep performing.

Made to Last

Chemical exposure and temperature changes are tough on rubber seals, but this o-ring is built to handle what you throw at it. The material resists swelling and cracking from chemical contact, so it keeps its shape and sealing ability season after season.

Good to Know

When you’re replacing this o-ring, it’s a good time to check the other pump seals and clean any chemical residue from the pump housing. A light coating of petroleum jelly on the new o-ring makes installation easier and helps prevent pinching during assembly.
