Frame pumps are highly underrated. IMPERO ULTIMATE II features a unique 2-stage head gasket to provide ultimate sealing and holding even when compared to lever chuck designs. Machined aluminum head with brass check valve ensures a lifetime of flawless use. Full aluminum barrel, handle and piston rod result in a pump that is competitive in weight with plastic designs while being significantly stronger, smoother and more durable.

Unique FlexWing Silicone bumpers on the head and handle tip are designed to accommodate tubing diameters from 1" (25mm) to 2.5" (64mm). An additional Silicone bumper on the main barrel protects paint, eliminates vibrations and noise, and also acts as a compression lock against the handle to keep it from moving until you use the pump. All IMPERO ULTIMATE frame pumps are hand assembled at the SILCA home office using Alcoa Aluminum extrusions and bar stock.
