TATTICO has 4 unique features: Inverted Design: TATTICO is designed backwards from most pumps. The hose and valving is hidden inside the inner tube rather than the outer cylinder delivering up to 10% more air per stroke compared to pumps of similar length. Adaptable Cup Seal: Other pumps seal with o-rings which lose effectiveness as friction heat increases. The TATTICO Adaptable Cup Seal grows with the tube resulting in ultimate efficiency at all temperatures. Hidden Heat Sink: There is a heat sink hidden at the end of the barrel which absorbs a high percentage of heat generated when pumping. This keeps the rest of the pump cool, even at high pressures. Twin Tube Insulated Grip: TATTICO handle uses 2 thin tubes separated by an insulating air gap to keep hands cool. This results in better grip and control without risk to hands even when inflating multiple tires to high pressures. SPECIFICATIONS: 6061 Alloy barrel and gripping surfaces High efficiency piston design Long extractable filler hose with locking presta/schrader chuck 100psi 9-1/2″ length Includes direct-mount bracket with retaining strap GETTING STARTED: The TATTICO mini-pump is ready to use when removed from the package.
