Getting them "started" over the valve tip is the more critical part, as they can be distorted or "scraped" at that time. Once started down the stem, keeping them "in line' is the key.
If the Viton (black, rubberish, rings), they're a bit more "forgiving" as they can stretch without distorting. Using the sheeth is still recommended. Usually, they can be pushed over the top of the guide by "hand". The Teflon-lined version (OEM) must be installed carefully, as the Teflon insert can easily come out, making it no longer "round".
SC's method of installing the heater hose nipple is the simplest way we've found, too.
FWIW

X 2 on the Viton teflon seals. Holds up better over longer periods of driving time. I have seen the all teflon seal become enough oblong to allow some seepage down the guide (stiff fit) where the viton/teflon seal gives on the guide.
X 2 on the nipple BFH does it every time. LOL.
