Silicon grease on dump hose connections?

I want my sewer hose connections to be tight.

I have used can of silicone spray - seems to work fine - cheap and easy to store.

What's it for? Just the peg + bayonet fittings?

My Rhino hoses came with the silicone grease already applied, inside the bayonet fitting, and the section of the fitting where it "screws" onto the hose itself.

In my opinion, the grease is actually working to enhance the waterproof nature of the connections, rather than provide lubrication or keep anything loose. That's the impression I get from where and how it has been applied by the manuf.

I recently moved to Rhino Extreme Sewer Hose because the connections are easier to unlock than the other brands I've used. The Rhino connections are just as tight, no leaks. As GordonThree stated, Rhino hoses are already silicon greased and, like him, I don't think the silicon is there to make the connections easier to unlock. They are just better engineered to lock and unlock smoother. However, before spending money on new hoses, try the silicon on the connection bayonets. Can't see the harm in that because the application of silicon isn't going to cause the hoses to suddenly come apart or leak. Anyway, I feel your frustration with those stubborn sewer hose connections and wish you the best!

A couple years ago I put some Dow 33 silicone grease on the dump hose twist lock attachment and life has become much easier! It is safe for rubber, unlike petroleum greases. It works wonders on door striker plates. I did try it on a sliding window and it helped, but over time it might attract dust.

It does not easily wash off and anything you put it on will be slippery for a long time. Its pricey and a tube will last a long time. Clicky

Its available in smaller quantities at paintball shops. Have not tried the plumbing grease as mentioned in an earlier post.

Thanks for all your responses, guys.
