JohnDow Industries 18" Replacement Polyethylene Funnel for JDI-8DCP & JDI-18DCP — Direct-Fit, Durable

JohnDow Industries 8DCP-Fun is an 18-inch polyethylene replacement funnel engineered to fit JDI-8DCP and JDI-18DCP pumps, restoring reliable fluid transfer and containment.

If you need to replace a worn or damaged funnel on compatible JohnDow pump systems, this 18" poly funnel is a direct-fit spare part manufactured for durability and straightforward installation. It’s molded in polyethylene to resist many common liquids and provides the same geometry and mounting interface used on JDI-8DCP and JDI-18DCP units. The design balances flow capacity with splash control so you can keep operations moving without improvising at the worksite.

Will this replacement funnel fit my JDI-8DCP or JDI-18DCP pump?

Yes—this component is produced specifically for the mounting pattern and throat diameter used on the JDI-8DCP and JDI-18DCP models. You’ll get a like-for-like match for bolt points and seating surfaces so no adapter is required.

• Designed for JDI-8DCP and JDI-18DCP compatibility
• Same inlet/outlet dimensions as factory part
• No modification or special tools needed for standard replacement

How durable is the polyethylene material for daily use?

The funnel is molded from industrial-grade polyethylene chosen for toughness and impact resistance. It stands up to routine handling, exposure to common pump fluids, and repeated installation cycles without cracking under normal use.

• High-impact polyethylene resists drops and knocks
• Chemical resistance suitable for many non-corrosive liquids
• UV-stable formulation reduces degradation from incidental sunlight

How easy is it to replace the old funnel with this part?

Replacement is straightforward: remove the old funnel, align the bolt holes, and secure with the original fasteners. The part is intentionally simple to minimize downtime and avoid specialty installation steps.

• Direct bolt-on replacement with existing fasteners
• No sealant or custom gaskets required for standard installations
• Typical swap can be completed in minutes by one person

What should I expect for flow and splash control compared to the original?

Flow characteristics mirror the original OEM funnel so you won’t see unexpected changes to transfer rates. The 18" profile helps reduce splatter while maintaining a generous mouth for fast filling and draining operations.

• Wide mouth for efficient filling
• Profile geometry reduces splash and overspill
• Consistent flow similar to the factory-installed funnel

Who is this for: This replacement funnel is intended for maintenance technicians, fleet managers, and operators who own JohnDow JDI-8DCP or JDI-18DCP pumping equipment and need a reliable, OEM-compatible spare part. It’s appropriate for workshops, service vans, and on-site field maintenance where a quick, durable funnel swap keeps pumps productive. Choose this part when you want a one-to-one replacement that restores original fit, general-purpose chemical resistance, and the same handling characteristics as the factory component.
