Abstract
Described are valve stems for wheels or other pressure vessels that may be installed from the exterior of a wheel or pressure vessel without access to the interior, pressure retaining areas. The valve stem may include a body with a barrel and taper. A neck may be between the body and a base that includes a flange, a flange landing, and an air aperture. An air channel runs vertically through the valve stem to allow air to pass from one side of the valve stem to another with a valve core or other flow control device. The base of the valve stem may include a groove that allows the valve stem to be installed into a hole by twisting such that the groove may ride along the rim of the hole and guide the valve stem into a fully seated and sealed position.
Claims14
A method for installing a replacement valve stem into a wheel hole of a wheel, the replacement valve stem comprising a body having at least one of a shoulder or a bead, a base comprising at least one helical groove, which breaches a flange landing of the base, and a neck positioned between the at least one of the shoulder or the bead and the base such that the neck has a smaller diameter than a diameter of the base and the at least one of the shoulder or the bead when the replacement valve stem is free of the wheel hole, the method comprising:
- cleaving an existing valve stem;
- separating the existing valve stem from the wheel hole;
- engaging the at least one helical groove with a rim of the wheel hole;
- and
- inserting the base of the replacement valve stem through the wheel hole from a wheel side of the wheel until the flange landing abuts and encircles an interior side of the rim of the wheel hole without inserting the body of the replacement valve stem through the wheel hole.

- and
- inserting the base of the replacement valve stem through the wheel hole from a wheel side of the wheel until the flange landing abuts and encircles an interior side of the rim of the wheel hole;
- and
- rotating the replacement valve stem until the neck of the replacement valve stem is positioned within the wheel hole.

- and
- rotating the replacement valve stem until at least one of the shoulder or bead abuts and encircles an exterior side of the rim of the wheel hole without the at least one of the shoulder or the bead entering the wheel hole.
