Molded Inlet Seal Assembly for Vactor 2100 Sewer Cleaning Trucks

The UEMSI G49654-SP Inlet Seal Assembly is a heavy-duty replacement seal designed for compatible Vactor 2100 Series combination sewer cleaning trucks.

Installed at the debris body vacuum inlet, this 14-inch x 15-inch & 14-inch x 16-inch inlet seal assembly helps maintain the sealed vacuum path needed for debris loading, sewer cleaning, catch basin cleaning, wastewater recovery, and other vacuum truck operations.

Unlike traditional multi-piece replacement seals that require the gasket to be hand-formed and glued onto a separate frame, the G49654-SP features a gasket that is completely molded and bonded to the inlet gasket frame. This integrated construction eliminates field forming and gasket glue seams, creating a more installation-friendly replacement for demanding municipal and contractor applications.

The assembly includes eight protruding attachment pins, along with the attachment nuts and washers required to mount the seal onto the compatible inlet weldment assembly.

Compatibility notice: Verify the truck model, build year, existing inlet seal part number, inlet dimensions, and inlet head weldment before ordering. These 14" x 15" and 14" x 16" seals is intended for compatible Vactor 2100 Series trucks using the G62222 transition inlet head weldment.

Why Choose the Molded UEMSI Inlet Seal?

Conventional replacement inlet seals may require a separate gasket to be manually shaped around the gasket frame and glued together. This process can be time-consuming, and failure at the glued seam can cause vacuum leakage.

The G49654-SP is supplied as a complete molded and bonded assembly. The gasket and frame arrive together as a single replacement component, reducing assembly work and eliminating the need to form and glue the gasket during installation.

For municipal shops, sewer contractors, and fleet maintenance departments, this design provides several practical advantages:

• Less preparation before installation
• No gasket hand-forming
• No gasket seam to glue in the field
• Consistent gasket placement on the frame
  

Recommended Applications

• Vactor 2100 Series combination sewer cleaners
• Municipal sewer cleaning trucks
• Vacuum truck inlet repair
• Catch basin cleaning equipment
• Wastewater recovery trucks
• Combination truck maintenance

Compatible Components

UEMSI G62222 Transition Inlet Head Weldment

The G49654-SP inlet seal assembly is designed for compatible Vactor 2100 Series trucks using the UEMSI G62222 transition inlet head weldment.

The weldment provides the mounting structure and transition point at the debris body vacuum inlet. The G49654-SP mounts to this structure using its eight attachment pins and included hardware.

The G62222 weldment is sold separately unless specifically stated otherwise.

Verify the Seal Size Before Ordering

This product is available in 2 configurations - 14" x 15" configuration and 14" x 16" configuration. 

Before ordering, verify:

• Truck model
• Truck model year
• Existing seal part number
• Inlet opening dimensions
• Inlet head weldment part number
• Number and location of mounting points
• Existing gasket and frame configuration

Signs the Inlet Seal May Need Replacement

Inspect the inlet seal when the vacuum truck experiences:

• Reduced vacuum performance
• Air leakage near the debris body inlet
• Difficulty loading debris or liquids
• Visible gasket tears or cuts
• Gasket separation from the frame
• Cracked or broken gasket material

A vacuum leak can occur elsewhere in the system. Inspect hoses, clamps, valves, tank door seals, tubing, gaskets, and related connections before concluding that the inlet seal is the only source of lost performance.

Installation Considerations

Installation should be performed by a qualified technician familiar with vacuum trucks, debris bodies, and combination sewer cleaning equipment.

Before installing the G49654-SP:

• Confirm the replacement part number and seal dimensions
• Secure and depressurize the vacuum system
• Follow applicable lockout procedures
• Remove the existing seal and mounting hardware
• Inspect the inlet head weldment for bending or corrosion
• Clean the mounting and sealing surfaces

Do not enter or work inside a debris body without following applicable confined-space entry, lockout, ventilation, and equipment service procedures.

Frequently Asked Questions

What is the UEMSI G49654-SP?

The UEMSI G49654-SP is a complete 14-inch x 15-inch molded inlet seal assembly for compatible Vactor 2100 Series combination sewer cleaning trucks.

The gasket is molded and bonded directly to the inlet gasket frame, and mounting hardware is included.

What equipment does the G49654-SP fit?

The G49654-SP is designed for select Vactor 2100 Series trucks using the compatible G62222 transition inlet head weldment.

Confirm the existing seal size, weldment, truck model, and build configuration before ordering.

What size is the inlet seal?

The G49654-SP is a 14-inch x 15-inch or 14-inch x 16-inch inlet seal assembly.

Is the gasket already attached to the frame?

Yes. The gasket is molded and bonded to the inlet gasket frame. The installer does not need to hand-form the gasket or glue a gasket seam during installation.

Is mounting hardware included?

Yes. The seal contains eight protruding attachment pins, and the required attachment nuts and washers are included.

Is the inlet head weldment included?

No. The G49654-SP is the inlet seal assembly. The compatible G62222 transition inlet head weldment is a separate component unless the listing specifically identifies the product as a combined assembly.

What is the benefit of a molded and bonded seal?

The molded construction eliminates the need to manually form a loose gasket around a frame and glue the gasket ends together. This can simplify installation and eliminate a field-glued seam that could later separate and leak.

Can a damaged inlet seal reduce vacuum performance?

Yes. A torn, separated, hardened, distorted, or incorrectly seated inlet seal can allow outside air into the vacuum circuit and reduce equipment performance.

Other system components should also be inspected when diagnosing vacuum loss.

Does the G49654-SP fit Vactor 2100i or HXX trucks?

Do not assume compatibility. Select Vactor 2100i and HXX trucks may use a 14" x 16" inlet seal assembly and a different inlet head weldment.

Verify the truck configuration and existing part number before ordering.

When should the inlet seal be replaced?

Replace the seal when inspection reveals tears, cracks, separation, deformation, hardened material, damaged mounting points, or an inability to maintain consistent contact with the mating surface.

Should the G62222 weldment be inspected during seal replacement?

Yes. A bent, corroded, cracked, or distorted inlet head weldment may prevent a new seal from seating correctly. Inspect the weldment and mating surfaces before installing the replacement seal.
