Airshot- replacement hose

I’ve had my air shot for a while and the hose needs to be replaced. I’ve got details on sizing (4mm ID, 8.5mm OD min 500mm length and able to withstand 11bar of pressure) but struggling to find a replacement hose. Any suggestions?

That’s 160 psi (ish) I don’t think that’s necessary because the isolation valve is before the hose. I suppose if the valve is clogged it might see 100psi or whatever.

is the OD critical? 4mm Automotive silicone hose is what I use for my home brew version. I think the OD is roughly 6.5.

I contacted Airshot by email when the hose in my 2 or 3 year old split. They sent me a complete new hose assembly foc. Great.

I’ve spoken to airshot and they can’t provide hose but gave me the dimensions. I can probably survive on a reduced OD…
