Three replacement washers for the connection between a CO2Art Pro-SE or Pro-Elite regulator and the CO2 cylinder. Choose the thread of your regulator: DIN477 / W21.8-14 / BS341 No. 8, or CGA320.
The washer is the seal between the regulator and the cylinder, so replace it every time the cylinder is refilled — a fresh washer is a leak-free connection every time.
Shipping and delivery
Free delivery on orders over €200; otherwise €9.99 in Europe and €14.99 for the rest of the world. Orders placed before 2 PM CET are usually processed the same day — a regulator may need a little longer, because every one is assembled and tested before it ships. Delivery is fully tracked with FedEx: 1–2 business days in Europe, 3–5 worldwide. Customs or import duties outside the EU are charged on arrival. Shipping policy · Returns
