Wacker Neuson 1000152534 Hose Fitting DKO-L DN16 M26x1.5 A3C

The Wacker Neuson is a genuine OEM Hose Fitting DKO-L DN16 M26x1.5 A3C designed for the TH627 hydronic surface heater. Sourced directly from Wacker Neuson, this fitting meets the exact specifications of the original component installed at the factory. It is a direct replacement for the TH627 (418-02) series, making it the correct choice when restoring your hydronic heating system to full working order. Keeping the fluid circuit sealed and flowing correctly depends on a fitting built to match — and this genuine part delivers exactly that.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact thread and seat specifications, ensuring a pressure-tight connection in the hydraulic fluid circuit with no risk of dimensional mismatch.
• DKO-L Bite-Type Connection — The DKO-L profile provides a secure, bite-type hydraulic connection that locks onto compatible hose ends cleanly and holds under working pressure.
• Correct Thread Specification — M26x1.5 male thread matches the factory port geometry on the TH627, allowing the fitting to seat fully without rework or thread chasing.
• TH627 Hydronic Heater Fitment — Confirmed fit for the TH627 (418-02) hydronic surface heater — verify your machine number against part number 1000152534 before ordering.
• Maintains Fluid Circuit Performance — A worn or leaking hose fitting disrupts fluid flow and pressure balance throughout the heating loop, reducing heat output and risking system damage. This replacement restores the circuit to proper operating condition.
• Fuel and Fluid System Safety — Hydraulic and fluid fittings in heating equipment carry hot pressurized fluid; using a correctly rated OEM fitting eliminates the risk of joint failure under thermal and pressure cycling.

A hose fitting in a hydronic surface heater connects the flexible hose lines to rigid ports within the heating loop, maintaining a sealed, pressurized path for the heat-transfer fluid as it circulates through the system. The DKO-L style uses a bite-type seat that forms a reliable metal-to-metal seal when properly installed, making it well suited to the temperature and pressure demands of hydronic heating equipment. When a fitting corrodes, cracks, or develops a leak, the heating circuit loses pressure and fluid, which can starve the system of flow and cause the heater to shut down or operate at reduced output.
