Been a lot of compressor threads lately so I just thought I would mention a couple of things about connecting to a bottle and general use of the fittings.

First off the simple bit. Guide to proper connection of whips and fittings from the BestFittings.

Now my way with the compressor to bottle. From left to right (all fittings are from BestFittings):
  • I use a spare DIN connector (blue dot) for the bottle because it makes my life simple, I like simple. If you are using a bottle to fill a gun the bottle DIN connector should have a restrictor fitted (see blue arrow for location) to slow the air from bottle to gun. You should remove this restrictor when filling the bottle. Normally a grub screw, 2.5mm allen key fits. By having a dedicated DIN connector I don't have to think about it, thinking hurts;
  • I have a 1/4BSP quick release (QR) socket (brown dot) fitted to the DIN connector so I can easily test the bottle pressure with a QR plug, fit a filter or connect the charging whip or anything else I want to do;
  • I use a double end male QR connector (red dot) to attach the charging whip to the bottle;
  • I have a 1/8BSP Female QR (yellow dot) connected to the charging whip (white dot);
  • The other end of the charging whip is connected to the charging device, neither are shown here);

one way valve from Best Fittings
I just test the bottle pressure before starting an then open the bottle valve when the line is close to bottle pressure. Close the bottle at the required pressure and bled using the compressor bleed valve. Personal choice, don't think one way is better than the other.

I guess that it depends on the compressor. With my Ying Tong the whip / filter pressure went up pretty quickly when I closed the bottle valve, it was a race to close the valve then open the compressor bleed valves. I'm with @BG1 on this, I have a one way valve between the filter and bottle whip. As soon as I hit 300 I open the compressor bleed and the one way stops the bottle emptying. It's also easier for filling, connect up and fully open the bottle valve rather than trying to open it slowly as the whip pressure approaches the bottle pressure. I had a spare female Foster connector so bought one of these for a few quid.
 
Bottle to gun but making the compressor to bottle easy.

You can buy these BestFittings started packs, they are cheaper from JSR 🤷‍♂️.

1/4 bsp Quick Release (QR) socket (male thread) and a 1/4 BSP bonded (AKA dowty) washer for the DIN connector. 1/8BSP Block Elbow, bonded and QR plug on the whip (You can buy this in parts or as a detach hose kit). This allows you to fit and detach or change the whip, easily test bottle pressure with a blanking plug.

Fit a QR female to the other end of the whip and you can swap gun fill probes that have a QR plug fitted or are made as a QR fill probe with ease.

Double ended QR plug to allow QR female to QR female connection for compressor to bottle connection.

I'm new to bottle filling with a compressor at home

Filled my guns with a bottle and compressor quite simple and I feel a bit thick asking this but I've got a 3 ltr bottle and compressor both with the Yellow and White dots (1/8BSP Female QR connected to the charging whip) so my fill probe plugs in and i can fill the gun with both.

Do I simply just need to buy the red dot (Double ended male QR connector)?? Id then have a compressor whip connected to bottle whip?.

Also is it beneficial to add a 1 way valve in to the mix?

I will one day buy the hills dry pac pro and include that

Yes. Brown dot is a female QR fitted dreckly to bottle DIN, no difference to a whip and female QR (yellow and white) connected to bottle DIN.

Also is it beneficial to add a 1 way valve in to the mix?
Yes for bottle filling only, DO NOT use for GUNS.

This is my way for the most benefit from a one way valve. I believe (because @BallisticBill told me) that air is like a sponge for holding water and as you squeeze that sponge (compress the air) the water is squeezed out. By using the one way valve as I do I think it gets loads of water out before it hits the rest of the filter chain.

I have noticed far more water in the first cotton filter (purple dot) since using the one way valve.

Double ended QR plug to allow QR female to QR female connection for compressor to bottle connection.
Thanks for this , I will be ordering some

Mint thanks ordered one might be able to top up my bottle with my hills hopefully Santa brings me a Hills Dry Pac Pro
