Sidek started in 1991 with a single valve and, with extensive industry consultation, has since developed a full range of reliable, high quality valving to suit all automotive applications. Sidek’s industry consultation and ability to deliver on customer requirements has propelled it to the forefront of the Australian LPG industry. Sidek’s high levels of applied ingenuity have created many state of the art valving solutions. The technology developed in the LPG industry is now also being applied in other industries such as the refrigerant, solar gas electric hot water systems and aeronautical industries.

Sidek’s attention to quality and reliability has led to independent testing by the South Australian Gas Company, Boral Energy and Origin Energy to comply with or exceed the requirements of AS/NZS 1425 (LP Gas Fuel Systems for Vehicle Engines). Sidek carries Australian Gas Association approvals on a large number of its products.

Sidek is a major supplier to Manchester Tank & Equipment Co. (Australia's largest manufacturer of LPG tanks) and with this association have become OEM suppliers for Mitsubishi Australia and Toyota Australia. Sidek is a leading supplier of aftermarket replacement valving, especially for 10 year statutory cylinder retesting.

Sidek’s extensive product range encompasses four valve and multivalve automotive systems. The individual components of these systems include service taps, auto fill limiters, level arms, pressure relief valves, valve plates, electronic senders and gauges, and a full range of forklift valving.
