GETOPAUTO UF106 DEF Urea Filter Kit — Direct Replacement UF106, 1-Pack, Protects Injectors & Pumps

GETOPAUTO UF106 is a diesel exhaust fluid (DEF) urea filter kit designed to protect SCR systems by trapping contaminants and helping keep urea dosing components working smoothly.

This UF106 kit from GETOPAUTO is built as a direct replacement for a range of urea filter part numbers used across heavy-duty diesels and buses. It fits many platforms — including Detroit Diesel, Cummins, DAF, Scania, PACCAR, BOMAG and more — and cross-references common OEM numbers like A0001421089, 4388378 and 1421089. The unit’s purpose is to filter DEF/AdBlue before it reaches the selective catalytic reduction components, helping preserve injectors, sensors and pumps by removing particulates and crystalline residues.

How does this urea filter protect SCR components?

The UF106 captures solid particles and crystalline build-up from diesel exhaust fluid before they enter the dosing and catalyst hardware. By keeping abrasive or clogging debris out of pumps and injectors, it reduces wear and the risk of flow restriction that can cause system faults.

• Traps particulates and solid contaminants from DEF fluid
• Minimizes injector and pump wear
• Helps reduce chances of dosing faults or flow restrictions

Will this GETOPAUTO kit fit my vehicle?

The UF106 is compatible with many commercial and off-road diesels; it lists multiple OEM cross-reference numbers to help you confirm fitment. Always compare the part number and physical dimensions with your current filter and consult your vehicle’s parts manual to ensure correct match.

• Cross-references: A0001421089, 4388378, 1421089 and others
• Common fitment: Detroit Diesel, EVOBUS, Cummins, DAF, SCANIA, PACCAR, BOMAG
• Check your vehicle’s manual or existing filter label before ordering

How do I install and maintain the UF106 urea filter?

Installation is straightforward for technicians familiar with DEF systems: depressurize the DEF circuit per manufacturer instructions, replace the filter element, and torque fittings to specification. For maintenance, follow your vehicle maker’s service intervals and use clean, certified DEF to limit contamination and prolong filter life.

• Follow vehicle-specific service procedures for DEF system access
• Use clean, ISO 22241-compliant DEF to reduce deposits
• Replace at manufacturer-recommended intervals or when service alert appears
