Fill whip - cosmetic or time to replace?

Protects the Arimid fibers from UV exposure, physical damage (abrasion) and chemical attack. The pattern of the fibers is what gives it the strength. There is nothing to protect the fibers and keep the pattern correct.

Replace, yes. Would I still use the hose until the new one shows up? don't tell OSHA but I would.

Replace. I have used this company for my whips: High Pressure Hose - August Industries Inc.

lol. their website must have a bug. they want $76 to ship 5 feet of hose and two connectors.

Looks like under $50 including shipping from August

August shipping is notoriously expensive.

August shipping is notoriously expensive.

seemed reasonable at around $10

Then things have finally changed. That is good news!

I ordered a DIN to NPT adaptor earlier this summer with very good shipping.
I can now use my DIN tank pressure checker on my bulk gas (He and O2) cylinders.

sort of. The aramid fibers do need to be protected from UV exposure and any chemicals as it degrades rapidly when exposed to pretty much everything. Physical abrasion and cutting is not something that aramid fibers are prone to and they are certainly more resistant to abrasion and cutting than the outer layers, but that's not really a design consideration.
The "pattern" that you're talking about is the braid and the outer layer does not have any effect on it's integrity. Braids when under tension will not move and when these hoses are under pressure the braids hold. Fire hoses are made similarly without any outer covering.

That said, to @guruboy that is likely a nylon braid btw. We don't use nomex in this type of application and the para-aramids *kevlar/twaron* are not white. They are naturally bright yellow and while they can be dyed other colors, they can't be turned white. Nylon is the grandfather of the aramid group and is a poly-amide so they are related, but it is not an aramid fiber.
