Hi all
Hope someone can help on this.
I’m looking to make a remote greaser for the stern gland on my boat. I have all the parts except one.
At the moment the stern gland has a grease cap. Unscrew fill with grease and screw it back on. Not very convenient and wastes more grease than it applies. So what I am looking for is a replacement cap which I can modify. If I use the existing cap and bu***r it up then I wont have anything. What I don’t know is the exact thread of the existing cap. ¾” BSP is too small and 1” BSP is too large. I therefore assume it to be 7/8” BSP (measured it at 1.096” or 27.8mm). I’ve tried ebay to no avail, tried online plumbing suppliers, tried screwfix. I’ve even taken the cap off and called in to Aquafax who said he’d never seen one so big (stop tittering).
So can anyone help? Attached picture of the offending item.
EDIT:
It's an old pic, the bilges have been cleaned and the clips doubled up.

All right so what is the technical name, sharp end or pointy end?

We changed ours to the automatic type, uses a resevoir behind and strong spring with a control valve to regulate the flow. We also fitted a longer remote flexible filling hose via a grease gun.
Both units were supplied via Jason Hatch of SOS24:7 / LBB
Hope this helps.

Graeme, Give ASAP a try I know they do the complete unit but no idea if they just do a replacement cap. the whole unit is only around a fiver, so it may be worth changing the whole thing,,,just type grease cap into ASAP search and Bobs your Auntie,,,
I'm Not CRAZY, my view on reality is just different to YOURS,,,

Hi Frank
Just had a look and can see what you mean. Not 100 percent sure but I think that the cup itself is an integral part of the stern gland. Will have to have a closer look next time down. Hope you are right and I'm wrong it'll make it so simple.

You could try a company called Pirtek they can usually match most thread sizes and may be able to help you out they have branches all over the place

I was going to say do make sure you have the right thread some of the old brass caps were Whitworth.

Hi minsadouble
Measured it with vernier calipers and that's the measurement I got on the od of the male thread. Unfortunatly can't get hold of a gauge plus I'm up here in Doncaster and boat down there won't be able to get down for a couple of weeks 
Very nice offer that you make though.
Bill, never thought of it being a Whitworth, boat is at least 40 years old and don't know what changes have been made.

If it's that old it may well be whitworth, I have been talking to Minesadouble on the phone and he maybe dropping some bits into the shop next week. Although not a stock item I guess what you really need is a correctly threaded extension with a tee off to go to the remote greaser with the cap back on top of that.

Well we managed to get down to the boat on Saturday to have another look.
Managed to clean all the crud and s*** away from the greaser and yes Frank you are right it is a simple screw in unit.
So problem solved.....almost. Just need to fit a 1/8 BSP elbow and away we go.
Thanks to all who replied.
