Helpful tips on identifying your exhaust elbow & flanges on your Perkins (Part 2)

In an earlier Tech Tip, Foley Tech Tip #60, we presented four common raw water mixing elbows and two exhaust flanges. We listed them by dimension and application. While these are the most common ones we provide, we offered $25 Foley Gift Certificates to anyone who could identify additional elbows and flanges. You rose to the challenge. Pictured below are three additional elbows.

ELBOW G

This cast iron elbow, sometimes identified as an 18450, is 7″ in overall length and forms a 90 degree down angle for a 3″ exhaust hose. It is female threaded (we supply it with a 2″ by 2″ pipe bushing to thread in) on the 3″OD end and 2″ OD on the unthreaded end. A heavy-duty fiberglass nipple is included with this elbow. It is commonly found on Perkins 4154’s. Our customers find the 2 3/8″ or 3″ exhaust hose less restrictive than the 1″ exhaust of ELBO B. This elbow, because it is cast iron will not last as long however as the aluminum ELBO B.

B. PN ELBOW H

This cast iron elbow, sometimes identified as an 18250 is similar in size and carrying capacity to ELBO G but is formed in a 30 degree angle.

C. PN ELBOW I
