Oil drain O-ring for GEKO oil heater with flue 25 kW, replacement sealing ring

Replacement O-ring designed specifically for the oil drain of GEKO oil heaters with flue and 25 kW output. This sealing ring fits into the drain connection to ensure a leak-free joint between the oil drain fitting and the heater body, helping to maintain safe and reliable operation of the fuel system during normal use and routine maintenance.

Advantages

The O-ring provides a precise sealing surface that prevents oil seepage at the drain connection, reducing the risk of drips and contamination. Made to match the original geometry of compatible GEKO heaters, it enables straightforward replacement during service without the need for additional adapters. The part supports routine maintenance by restoring correct sealing performance and contributes to safer handling of fuel during draining procedures.

Suitable for

• Maintenance and repair of GEKO oil heaters with flue and 25 kW heat output
• Replacing worn or damaged drain seals to stop oil leaks
• Routine service tasks that require draining or reconnecting the fuel line
• Workshops and field service technicians performing heater servicing

Key specifications

• Function: sealing ring for oil drain connection
• Compatibility: designed for GEKO oil heaters with flue and 25 kW output
• Material: elastic sealing elastomer suitable for fuel contact
• Shape: circular O-ring profile matching original drain geometry
• Operating use: intended for use in fuel/oil drain assemblies

How to use

Ensure the heater is turned off, cooled and that any residual pressure in the fuel system has been relieved before beginning. Drain or disconnect the oil drain fitting according to the heater manufacturer’s service instructions, remove the old O-ring, and clean mating surfaces of any deposits or residue. Install the replacement O-ring into the drain groove, taking care not to stretch or nick the seal, then reassemble the drain connection and tighten to the specified torque or hand-tight specification. Inspect for leaks after recommissioning and perform a short operational check to confirm correct sealing.

Usage recommendations

Replace the O-ring during scheduled maintenance or whenever signs of hardening, cracking, or leakage appear. Use only compatible seals and follow the heater manufacturer’s safety procedures when handling fuel or performing service work.
