Donaldson P112609 Rubber Hump Coupler Hose Connector

The Donaldson P112609 is a rubber hump coupler (Hump-R) designed for use in air intake and induction ducting systems. Engineered by Donaldson Filtration — a global leader in industrial and commercial filtration — this flexible rubber connector bridges sections of intake tubing while providing critical flexibility to absorb vibration, thermal expansion, and minor misalignment between components.

Key Features:

• Flexible rubber construction absorbs vibration and reduces stress on intake system components
• Hump-style profile accommodates angular misalignment and lateral movement
• Designed for use with Donaldson air intake ducting and filtration systems
• Durable rubber compound resists cracking, aging, and temperature cycling
• Provides a secure, airtight seal between intake duct sections
• Direct replacement for OEM Donaldson intake system applications

The Donaldson P112609 Hump-R coupler is ideal for heavy-duty trucks, commercial vehicles, off-highway equipment, and industrial machinery that use Donaldson air intake systems. Its flexible hump design helps protect upstream and downstream components from vibration fatigue, extending the service life of the entire intake assembly.
