Volume: 120 ml + 120 ml (4 + 4 US Fluid Ounce). Perfect volume if you need to laminate large baits of around 10 inch or use for smaller multi-cavity moIds.
Material: Aluminum. Aluminum alloy recommended itself as a light and durable material, which is suitable for moId injectors.
Rubber sealing rings. There are two rubber sealing rings to prevent plastisol from leaking as well as to create more pressure during pumping.
Injection port: 5/8" injection. This diameter has become a standard over the years for soft plastic lure moIds. It's an optimal size to create targeted pressurized plastisol flow.
We recommend to put a marking on the piston rod to determine the safe amount of pressure, which can be applied to piston, without accidental exposure of the cap.
