Suction Pipe for FillRite Sotera 415 Series DEF/AdBlue Transfer Pumps

Description

When your Sotera 415 DEF pump won’t prime properly or you’re getting reduced flow from your AdBlue dispensing system, there’s a good chance the suction pipe needs attention. This replacement suction tube is specifically engineered for DEF compatibility and designed to handle the demanding requirements of diesel exhaust fluid transfer applications. Whether you’re running a shop or managing a fleet, a properly functioning suction line keeps your DEF system working smoothly.

What You’re Getting

• Polypropylene construction that’s fully compatible with DEF and AdBlue fluids without degrading over time
• 3/4 inch hose barb fitting with EPDM o-rings for a leak-free connection that handles system pressure
• Cut-to-length design that lets you customize the pipe for your specific tank depth or application
• Includes stainless spring reinforcement to prevent collapse during suction operation

Built for DEF Service

The Sotera 415 series pumps are widely used for transferring diesel exhaust fluid in agricultural and commercial applications. These pumps handle the corrosive nature of DEF while maintaining the fluid purity required for modern emissions systems. This suction pipe is designed to work with the pump’s positive displacement action to provide consistent flow from your DEF storage tanks.

Made to Last

DEF is tough on equipment, but this suction pipe is built to handle it. The polypropylene material resists the corrosive effects of urea-based fluids, while the EPDM o-rings maintain their seal even with temperature changes. The stainless spring reinforcement prevents the tube from collapsing under vacuum, ensuring reliable flow even when your tank gets low.

Good to Know

You’ll need to cut this pipe to the right length for your application—measure from your pump connection down to about 2 inches from the bottom of your tank. Make sure to use a clean, sharp cut to ensure proper fit on the barb fitting. The spring should extend the full length of the tube to prevent any kinking or collapse during operation.
