The oxygen cylinder pressure gauge produced by East Asia Meters strictly implements the medical grade oil-free degreasing process, ensuring absolute safety in use under hyperbaric oxygen environment through multiple precision ultrasonic cleaning. As a source physical manufacturing factory with more than thirty years of industry experience, we directly connect with global buyers, eliminate all trade intermediate links, and provide you with highly competitive direct supply prices and shorter delivery cycles.
Oxygen cylinder pressure gauge is mainly used in medical oxygen cylinders, industrial welding and cutting, laboratory gas control and gas filling stations.
The product strictly follows the oxygen instrument manufacturing standards and passes four ultrasonic degreasing and cleaning processes to ensure that there is no oil residue inside. This fundamentally eliminates the risk of spontaneous combustion or explosion caused by contact between high-pressure oxygen and oil, and ensures the extreme safety of medical and industrial gas.
The core pressure sensing element is made of high-quality phosphor bronze, which has excellent elastic modulus and fatigue resistance. After 10,000 full-scale cyclic pressure tests, the instrument can still maintain the initial measurement accuracy, effectively extending the service life of the product in frequent filling environments.
The housing is made of high-strength steel and has been electrostatically powder-coated for excellent corrosion and impact resistance. Whether on an outdoor welding site or in a hospital ward, the case provides strong protection for the precision movement inside, reducing damage from drops.
The dial is prominently printed with a striking red no-oil sign, which meets international traffic safety warning standards. Even at operation sites with low light, staff can clearly distinguish the purpose of the instrument, effectively preventing the mixing of oxygen meters and ordinary gas meters.
The internal movement is machined by automated CNC machine tools, and the gear meshing tolerance is controlled within a very small range. This ensures smooth and non-stuttering pointer operation, effectively reduces back-difference and value indication errors, and provides gas regulators with an accurate reading reference.
The joint thread is strictly gauge tested to ensure perfect match with the gas cylinder pressure reducing valve. In conjunction with the factory’s 100% factory airtightness test, it solves the common interface micro-air leakage problem in the industry and ensures the overall integrity of the high-pressure gas transmission system.

When purchasing, this group places greater emphasis on the oil-free certification and medical-grade manufacturing qualifications of Hangzhou East Asia Instruments to ensure the safety of clinical oxygen use.
Applicable to suppliers who provide oxyacetylene cutting systems for shipyards and steel structure plants. The Hangzhou East Asia Instrument’s rugged steel shell design is well-suited to harsh industrial construction environments and can effectively cope with collisions and metal dust pollution.
standard gas equipment distribution for the global market. Hangzhou East Asia Instruments supports the customization of various pressure units and thread specifications, assisting traders to quickly meet the access standards of different countries and regions, and enhance their competitiveness in the global supply chain.
Before installing to the oxygen cylinder system, it must be confirmed that all connecting tools and hands are free of any oil contamination. The use of oil-containing sealing strips is strictly prohibited to prevent dangerous reactions.
A wrench should be used to fix the hexagonal position of the joint during installation. Tightening the instrument by hand rotating the case is prohibited, and the instrument dial should be kept in a vertically upward position.
When opening the cylinder main valve, be sure to act slowly to prevent the instantaneous high-pressure airflow impact from causing the instrument pointer to bend or the Bourdon tube to permanently deform, and ensure that the measurement data is true.
It is recommended to approve the accuracy of the instrument every six months. If the pointer cannot be reset to zero or the housing is significantly deformed, it must be stopped immediately and replaced by professionals.
