Default Tips for solder sucker?

My solder sucker tip has finally melted back to the point where it doesn't work so well.

I bought it cheap, and it's unbranded. Heavy though, and nicely made.

I want to buy new tips, which means the new tips need to screw on to the old body.

I have measured the old tip thread as well as I can. The thread pitch is only 5 turns, so very hard to measure accurately.

Outside diameter (OD) 0.7215" or 18.32mm
Pitch(metric): either 0.75mm or 0.8mm
Pitch(imp): 30 or 32 TPI

Can anybody match this up?

How about a photo so we have some idea what you are trying to match?

Do those not fit yours?

I used to buy those metal solder suckers at surplus. I found the sucker itself was less expensive than the replacement tips.

I've used little ones like that and the main issue I had with it is getting a seal so it actually extracts the solder. Instead I use the old Edsyn like this

The Original Deluxe SOLDAPULLT: EDSYN Inc.

Similar but bigger. It moves enough air that if you _don't_ have the best seal it clears the hole anyway. For a while I was using one from DigiKey

https://www.digikey.com/product-deta...K412-ND/243483

It LOOKS the same and works the same UNTIL IT BREAKS internally. I went through 3 or 4 in a few months (we bought a bunch at work). I'm back to the Edsyn and have no problems. These gadgets need to be kept clean and lubed. The lubricant is silicone grease without zinc oxide in other words, clear heatsink grease. I found that swimming pool O ring seal grease works as well, cost a little less and is much easier to find.

My sucker is similar to the one pictured and is probably 20 years old and the tip shows no signs of melting at all. Some tips must be made of better material than others.

Slip a short length of silicone tubing over the teflon tip.
Seals perfectly to pcb, replace as required.

You can put a long bit on and pull it down as it wears away.
It is a good tip saver.
