This HDI Marine straight mixing elbow (SM4-6) is universally used for custom exhaust and is a great substitution for a fabricated mixing elbow. This allows you to separate the elbow for maintenance/cleaning unlike a welded in place mixer.
Straight mixer kit includes mixing elbow, weldable, stainless steel flange and stainless v-bandclamp. Flange is designed to be welded to stainless tube.
NPT thread for a 2” (51mm) OD water connector (not included)
