The present invention provides an apparatus, system and method for replacing seats utilizing J-shaped hooks on a puller shaft that may be compressed to pass through the seat and expand back to engage the seat from below for pulling upward and removal.

An auxiliary fixture for a tire pressure monitoring device has a handle, a positioning base, and a holding lever. The positioning base is connected to the handle and has a pivot segment and a clamping segment. The pivot segment is deposited on a rear side of the positioning base and is pivotally connected to the handle. The clamping segment is deposited on a front side of the positioning base, is connected to the pivot segment, and has two adjusting elements and a pushing pin. The adjusting elements are deposited on a front side of the clamping segment, and the pushing pin is deposited between the adjusting elements to press against the tire pressure monitoring device. A distance between the adjusting elements can be adjusted to enable the adjusting elements to clamp the tire pressure monitoring device. The holding lever is connected to the handle.

A mini pump comprising a linear hand pump assembly and a valve core tool is disclosed. The linear hand pump assembly is configured to operate along a longitudinal pump axis and comprises a first end and a second end opposite the first end. The valve core tool is releasably coupled to the first end and has a central tool axis and a cavity centered on, and running parallel to, the central tool axis. The cavity passes through at least one of a top surface and a bottom surface of the tool and is shaped to mate with a valve core such that, with respect to rotation about the tool axis, the valve core is rotationally fixed to the tool. The pump axis and the tool axis are collinear when the tool is coupled to the assembly. The valve core tool and the pump assembly may be threadedly coupled.

Example valve stem and plug connections and example staking tools are described herein. An example apparatus includes a valve plug having a first side, a second side opposite the first side and a bore extending from the first side to the second side. A first portion of the bore is tapered from a first diameter to a second diameter smaller than the first diameter. A valve stem is disposed within the bore of the valve plug. The valve stem includes a first section, a second section and a third section between the first and second sections. The third section is tapered from a third diameter to a fourth diameter smaller than the third diameter. The tapers of the first portion of the valve plug and the third section of the valve stem, when engaged, create a frictional force that resists movement of the valve stem out of the bore.

A system for removal of Moen cartridges or cores and sleeves from plumbing valve bodies is facilitated with a tool having concave, cylindrical billed jaws on a vise-grip pair of pliers and a specially built extraction tool on the screw end of the vise-grip. The outer shape of the billed jaws matches the outer diameter of the cartridge's core. The tool's bills lock on the inner core of the cartridge. Ideally the inner core and outer sleeve will both be extracted with the tool's bills. When conditions are not ideal due to hardened or broken o-rings and corrosion, rotating the tool and cartridge are required to free them from the valve body. The Pasco stem and cartridge puller attached to the screw end of the vise-grips is used to extract the outer sleeve of the cartridge after the inner core has been removed.
