What is the Taisei Kogyo G-UL-10A-40UW filter element?

The G-UL-10A-40UW is Taisei Kogyo's filter element for its G-series hydraulic filter housings — a pleated stainless-mesh element with grey metal end caps, made in Japan. The factory box says it plainly: FILTER ELEMENT, TAISEI KOGYO TOKYO JAPAN, with the label G-UL-10A-40UW, SEL000448, MADE IN JAPAN and the Taisei mark; the end cap carries the same G-UL-10A-40UW engraving. Factory-new in the original box and bag, 3-month warranty as recorded at intake on 11 December 2025. All seven photos and the inspection video show this exact element.

Fitting the G-series element

Taisei Kogyo's G-series filters are the return-line and tank-mount filters on Japanese hydraulic power units, and the G-UL-10A-40UW is the element they consume: the pleated stainless mesh is washable-grade media, so on a clean system it services with a solvent wash rather than a replacement, and the perforated core keeps the mesh from collapsing under the differential. The end caps seal against the housing bore, flow runs outside-in, and the engraving on the cap means the correct part number is still legible after years in service — the check a maintenance tech makes before ordering.

The element in this record is factory-new in the Taisei Kogyo box: the blue-and-white carton with the Tokyo address, the SEL000448 label, and the element bagged beside it with the mesh weave photographed straight-on so the pleat spacing and weave regularity are verifiable before purchase.
