Product Details

The Marshall Excelsior MEGR-253 Excelaflo Automatic Changeover Regulator ensures uninterrupted LP gas service by automatically switching from an empty service cylinder to a reserve cylinder. This professional-grade regulator is designed for bulk propane systems in RV, marine, and commercial applications where continuous gas flow is critical.

Key Features:

  • Automatic changeover function switches between cylinders without service interruption
  • Easy-to-read visual indicator: green shows normal operation, red signals when service cylinder is empty
  • Excelaflo design ensures consistent gas flow and pressure regulation
  • Durable brass construction for long-lasting performance in outdoor environments
  • Two-stage regulation provides stable outlet pressure regardless of cylinder pressure
  • Designed for use with standard POL cylinder connections

The MEGR-253 is ideal for applications requiring continuous propane supply, including RVs, food trucks, emergency backup systems, and remote heating installations. The visible indicator system allows users to identify when it's time to replace the empty cylinder before the reserve runs out, ensuring you're never caught without fuel.

I was stoked that after reading other reviews that there was no shipping charges for my purchase. Thank you!

Easy transaction

The only thing negative I can say is I didn't receive emails stating the item was shipped with a tracking number. I did receive the part quickly so I can complain too much about the lack of emails. I will use Autoplicity again in the future.

Great Experience, product as described, quickly shipped.

Eh

Glad there is next day shipping available!

The service and product was excellent!

Execellent retailer. Easy to buy from online. Got product quickly at a great price. I highly recommend!

Best Price on the Net for K&N System for my 2012 HEMI RAM. My Order 18270 is shipping today and I can't wait to get it installed!

After having trouble completing the payment process through Amazon, I was able to complete my payment information directly on the Autoplicty website and submit the order quickly. The process was easy and fast. They had the best overall price (item plus shipping) I could find on the net. The item was shipped promptly and arrived in great condition. A quality merchant all the way around.

Best price by far! Very fast shipping at a very reasonable price. Will definitely use again!

easy ordering!

Easy to deal with about shipping questions, great prices, and friendly customer service. One of the few places who says "I'll return you call" and actually does. Thanks...

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)
