Advice Needed On Pushing Stuffing Box Hose Onto Shaft

[macbeth]

I'm replacing the hose that runs from the inlet shaft to the stuffing box. The bronze stuffing box has a smaller diameter than the shaft. Any ideas on how to make the hose (about 6" long) a bigger diameter at one end ? Putting it in boiling water, liquid soap, hire Superman ?

Hot air gun works wonders with hoses, just don't melt it.

the Compass Marine" website has an excellent "how to" on stuffing boxes.

If the hose is proper stuffing box hose I don't think you could stretch it to fit the larger diameter. The original hose may have been proprietary to the manufacturer.
How much of a difference is their in the two diameters?

Trim a bevel in the hose end of course but leave it in the hot water for a while. Don't just microwave it for 30 sec. and try to stick it on. Let it heat soak for a few minutes. A little silicone lube will help. A heat gun is too radical in the wrong hands.

A bevel ??? Do you mean cut the hose so that the leading edge is at a 45 degree angle ?

Thanks to everyone for responses so far.

Yes, I've reviewed the Compass Marine Website. Great stuff. We should give him a medal !

Difference in diameters is about 0.15", but I'm using Buck Algonquin hose which is very stiff !

Original hose is 1988 era ! Quite possible proprietary. And not as good as Buck.

do you have a thru hull plug handy? Put the piece of hose over it to stretch it out a bit. Lube up the plug with liquid soap or whatever you happen to have handy, then let it sit for a bit to "take set." Pull it off, then quickly put it in place.
