MIXER ELBOW 3.50D OUTLET 316L. MATTE FINISH WITH 1" REMOVABLE INSULATION BLANKET, GREY IN COLOR. 88.90mm/3.5 D. VENDOR # GM117154

Overview:
The Kohler GM117154 is a wet exhaust elbow designed for Kohler engine/exhaust systems. This component facilitates the routing of exhaust gases in systems where moisture is present and is built to Kohler’s standards for durability and performance. Most of the OEM mixers had a design flaw from what we've seen, so we re-engineered this to perfection and try to keep these on the shelf, ready for customers just in case.

Features & Specifications:

  • Type: Wet exhaust elbow

  • OEM Part Number: GM117154

  • Compatibility: Designed for use with Kohler generator or marine exhaust systems (verifiable via engine model and system layout)

  • Materials & Construction: 316L, intended to withstand high temperatures and the corrosive effects of wet exhaust environments.

  • Connections: Includes flanges for attachment to exhaust piping, water inlet connection (≈ 23 mm diameter) for cooling water / mixing water in the exhaust stream. Please enquire about the gasket if needed.

Included Accessories:

  • Comes with a grey insulation blanket for thermal protection and noise mitigation. These blankets help reduce heat loss, protect nearby components, and dampen exhaust noise.

Benefits:

  • Improves safety by limiting surface temperatures in exhaust routing

  • Enhances system lifespan by protecting components from heat damage

  • Maintains exhaust performance while minimizing the risk of overheating or warping in adjacent parts

Typical Uses:

  • Marine generator wet‐exhaust applications

  • Standby or industrial generators with wet exhaust manifolds

Additional information

Mixer Tank

While 316L stainless steel performs well in many marine environments, AL6XN offers a significant leap in corrosion resistance and long-term reliability — especially in high-temperature, high-chloride conditions common in exhaust systems.

Why AL6XN Outperforms 316L

Superior Corrosion Resistance: AL6XN’s high molybdenum content (6%) gives it exceptional resistance to pitting, crevice corrosion, and chloride stress cracking, even in seawater and salt-laden air where 316L begins to break down.

Longer Service Life: This alloy holds up against constant exposure to exhaust condensate and salt spray, dramatically reducing the risk of premature failure or pinhole leaks over time.

Better Performance in Heat & Pressure: Ideal for mixer tanks and other exhaust components exposed to hot exhaust gases and fluctuating temperatures — maintaining structural integrity where 316L may fatigue faster.

Lower Lifetime Cost: Though AL6XN carries a higher upfront cost, its extended service life and reduced maintenance needs make it the most cost-effective material over time.

Peace of Mind: Choosing AL6XN means choosing maximum reliability for your exhaust system — and fewer costly repairs down the line.
