Wacker Neuson 5200015375 Seal Flange P-5000112006

The Wacker Neuson Seal Flange P- is a genuine OEM component designed for the HI260 and HI1000 Indirect Air Heater series. As a direct factory replacement, it meets the exact material and dimensional requirements specified for these indirect-fired heater units. Cross-reference part number against your machine's serial number and model to confirm fitment before ordering. This is the correct OEM-sourced part for HI260 Oil Heater with Tank, HI1000 Diesel, Gas, and DGM variants, covering both surge brake and electric break configurations.

Key Features

• OEM Sealing Integrity — Manufactured to the original compression and material specification, ensuring a fuel- and heat-resistant seal matched to Wacker Neuson heater system pressures.
• Direct Flange Replacement — Designed to seat and torque exactly as the original flange, with no reworking of mounting surfaces required.
• Broad HI-Series Fitment — Compatible with HI260 and HI1000 model families, including Diesel, Gas, and DGM variants in both surge brake and electric break configurations.
• Combustion System Protection — A correctly seated flange seal prevents heat and fuel vapor bypass, keeping the heater's combustion path sealed and output consistent.
• Fuel System Safety — A worn or failed flange seal on a diesel or gas indirect heater can allow combustible vapor leakage; replacing with the correct OEM part restores the designed containment barrier.

A flange seal creates a pressure- and temperature-resistant barrier at the joint between two mating components in the heater's fuel or combustion system. It prevents hot gases, fuel, or combustion byproducts from escaping the sealed pathway, which is critical to both heater efficiency and safe operation. When a flange seal degrades — through heat cycling, compression fatigue, or chemical exposure — leaks can develop that reduce heat output, cause fuel odor, or create a fire hazard, making timely replacement essential.
