42mm to 28mm Bottle Adapter

[el manana]

Does anyone know if they exist or how to make one? So something like a CNOC Vecto 42mm bladder could be attached to a 28mm Mini Sawyer instead of having to buy the 28mm Cnoc?

Source make these adapters but not for this size:




It looks like the Hydrapak 28mm Adapter combined with the Hydrapak 42mm plug and play would work but a pricey and pointless solution

I’ve seen a couple of 3D printable ones but I don’t think the threads were quite right so they leaked. Might be on Thingiverse

There's a thread over on BPL about this. If you don't want the Hydrapack adaptors, you can can rip the filter part out of a retired Befree filter.

Anyone got an old BeFree that no longer works?

Must be loads out there

There is a company based in Israel (I forget their name) that sells water bottle/ bladder thread adapter kits, with a bite valve hose included...I bought one a few years back on ebay.
I used one of the adapters, and the hose for my old Decathlon 3L water bladder.
If I can find out who they were again I will let you know.

Probably Source which is an Israeli company and is mentioned in the first post but they don't make a 42mm adapter, they have Sigg and Nalgene sizes only.

I have read the odd mention of Trek-Liters giving up on the Befree and switching...

I wonder if that is because a BeFree filter is only good for up to 1000 litres (about 267 US gallons...When a Sawyer Mini is good for up to 100,000 US gallons or 375,000 litres), and/or perhaps because each BeFree filter costs more than an entire Sawyer Mini kit?

That's not it...HydraPak is US Based (in Oakland California).

Update: Just found them...They are called Source Outdoor, from Tirat Carmel in Israel.
The product you want is called "Covertube", which is a kit which comes with several different sized bottle thread adapters:

Convertube Adaptor

The Convertube Adaptor converts a water bottle to a hydration system for hands-free drinking from almost any bottle.

(Very) late update on this.

@Bopdude kindly sent me an old blocked BeFree filter and detaching the filter from the cap was surprisingly easy; just a firm push.

I tried it on a Cnoc Vecto 42mm bladder and the thread seemed quite a poor fit. When I tested it, I was not surprised to see it leaked a bit, enough for it not to be fit for purpose. I did wonder if this was an old BeFree filter and the thread was not compatible with a new Cnoc Vecto I had? - I assume people are using the BeFree filter/Cnoc combo without issue?

I've recently bought a Hydrapak Seeker 42mm with their version of the BeFree style filter.
The BeFree cap fits much better on this...





There is a very slight leak takes 3-4mins to appear and is a couple of drips per minute. Slow enough to still make it functional, i wouldn't have a problem in using it to collect camp water and carrying it for a while, but certainly wouldn't leave it lying down in the inner tent. Forcing water through the Sawyer Mini didn't increase the leak rate.



Maybe a newer BeFree filter would be a better fit on the Hydrapak bladders too?

On Ebay there is a non-UK seller making 3D printer 42mm->28mm adapters (states Hydrapak to Sawyer Squeeze, and wont work on the Mini - why?...). From what I understand it would be very difficult to get a 42mm adapter that works on all bottle makes(Hydro, Cnoc, BeFree etc) as they can all have slightly different thread pitches. Anything made on a 3D printer would have to be food grade safe, and many plastics are no longer food grade once they've been through a 3D printer.

In areas with peaty/discoloured water which might prematurely block the Hydrapak filter, I'll be leaving it behind and using the bladder with the Sawyer Mini. I'll probably just get the official Hydrapak adapter set to make this leak free.
