Abstract
A valve coupler for a quick inflation device includes a sleeve having a longitudinal passage. A sealing member is mounted in a first end of the sleeve. The first end of the sleeve further includes a shoulder formed on an outer periphery thereof. A first jacket is mounted around the first end of the sleeve. The first jacket includes a first end bearing against the shoulder of the sleeve. The first jacket further includes a second end extended beyond the first end of the sleeve. A second jacket includes outer threading on an end thereof for engaging with inner threading of the first jacket. The inner threading of the first jacket and the outer threading of the second jacket are fixed together. The end of the second jacket includes an end face that encloses the sealing member. The sleeve is not moved when the valve coupler is engaged with a tire valve for inflation, thereby preventing damage to the sealing member.
