Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.040". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Durable, Reliable RV Sewer Hose
Style: 20' Rhino Sewer Hose
The Camco RhinoFLEX sewer hose appears to be extremely durable and tough — exactly what you want when it comes to RV sewer equipment. This is one product where you absolutely don’t want leaks, and this hose feels solid and dependable. I really like that it comes in two 10‑foot sections. You only have to use the length you actually need to reach the dump station, which keeps things cleaner and easier to manage. The fittings lock on securely, and the hose holds its shape well during use. Overall, a strong, well‑designed sewer hose that gives you confidence every time you dump your tanks.

Easy Install; clear elbow a plus!
Style: 20' Rhino Sewer Hose, Style: 20' Rhino Sewer Hose
This set up was very easy to connect. Strong hooks at the end that attaches to the tank and lock in place. To lock it, I had to use brute force! Omg. :-) I’m very happy with the clear elbow. I had always shut the tank before it was clear, I am sure. One concern, I saw leakage between the clear elbow and the adapter that connects with the sewer line. 30 seconds later the leak healed it seal, so to speak

Best poo tote out their
Size: 36 Gallon, Style: Heavy Duty (2 Wheel)
"I recently purchased the Camco Rhino portable RV toilet tank and I have to say, I am absolutely thrilled with my purchase! This heavy duty tank is exactly what I was looking for and it has exceeded my expectations in every way. First of all, the tank is incredibly durable and well-made. I can tell that it's built to last and withstand even the toughest camping conditions. And despite its tough exterior, it's surprisingly easy to transport and set up. But what really sets the Camco Rhino tank apart is its functionality. The tank is designed with the RV user in mind and it has all the features you could possibly need for a comfortable and convenient camping experience. The tank is easy to fill and empty, and the built-in spout makes the process a breeze. Overall, I am so happy to have found the Camco Rhino portable RV toilet tank. It has made my camping trips so much more comfortable and enjoyable, and I would highly recommend it to any RV enthusiast out there. Thank you Camco Rhino for creating such an amazing product!" Also after receiving my tank tote it was broken. So I called camco and spoke to a very nice person, without have to go through a phone tree. It's always reassuring to know that a company stands behind their products and is willing to make things right if there are any issues. Camco Rhino has excellent customer service and is committed to ensuring their customers are satisfied with their purchases. I would definitely feel confident buying from them in the future knowing they take care of their customers.

great product
Size: 36 Gallon, Style: Heavy Duty (2 Wheel)
very sturdy fits almost my whole tank inside it although it makes it kind of too heavy to move around. It’s really easy to install. It has all the hook ups. It looks great. The size is perfect. Doesn’t seem to make any noise and it’s thick sturdy and and nothing leaks out all the connections are there and they connect very well.
