Look like they are poly butyl pipe fittings. Similar listed here:

If they are polybutylene you might want to look at replacing fittings and pipe. Do a search on the problems associated with polybutylene pipe and fittings.
Whale fitting in the old days were grey..... new ones are white and different design. Photo shows what was on my 1986....I looked those up. Whale type Doesn’t match... Shannon
Thank you sir!
If they have ferrules, then they are ferrule fittings. The ferrule fittings for plastic hose that I used to use in Industry, were made by Parker Hannifin. We bought them wholesale, but I think that Mcmaster Carr carried them in small quantities. They had pretty dainty torque specifications. Over-tightening was not a good thing. I seem to remember seeing some similar fittings in the plumbing section of Home Depot. I do not know if the ones I am talking about will be the same as yours. The color of the plastic is different. It may be a different material.I can’t seem to discern the Name of these gray plastic fittings. I know it’s not pex. And it is a 1/2” NPT. There is a ferrel on the hose to provide a water tite fit.

Been there and done that. Nope. Ditto the big box stores. If you search online, there are some sites that carry this stuff. I have a few spares, just in case. Otherwise, this product is pretty reliable if installed properly.Also check at RV parts departments. They usually have a good supply of these fittings.
