Is the Stainless Steel Hydraulic Quick Coupling with Valve, Socket GW BSP/NPT, TEMA Standard suitable for gas installations and which sizes include the additional O-ring?

Stainless Steel Hydraulic Quick Coupling with Valve, Socket GW BSP/NPT, TEMA Standard is suitable for gas installations. The product description states that an additional O-ring is included for gas suitability in all sizes except 3/16". Available socket sizes are 3/16" and 1/4" (socket side only); therefore the 1/4" size includes the additional O-ring, while the 3/16" size does not.

Can the Stainless Steel Hydraulic Quick Coupling with Valve, Socket GW BSP/NPT, TEMA Standard handle pulsating pressure, and how should working pressure be adjusted for long-term use?

Stainless Steel Hydraulic Quick Coupling with Valve, Socket GW BSP/NPT, TEMA Standard Format can be used with pulsating pressure, but its long‑term performance requires derating. For pulsating or fluctuating loads the maximum working pressure must be reduced by 50% (relative to the stated up to 300 bar, depending on diameter). The coupling is built from AISI 316 stainless steel with Viton seals and a 4:1 safety factor, but halving the working pressure for pulsation ensures seal and component longevity and prevents fatigue failure. Operating temperature range is −20°C to +200°C; the coupling is suitable for hydraulic oils and a wide range of industrial media.

The TEMA STANDARD quick coupling socket from the NORDIC RANGE is a robust and reliable solution designed for demanding industrial and hydraulic applications. Equipped with an integrated shut-off valve and internal BSP or NPT thread, it ensures secure and efficient connections. An additional O-ring (except in size 3/16″) makes it perfectly suited for gas installations, while the built-in safety ring prevents accidental disconnection, enhancing operational safety. This one-sided shut-off coupling is available in sizes 3/16″ and 1/4″ (socket side only), making it ideal for specialized use. Manufactured from premium stainless steel AISI 316, it guarantees durability and resistance to corrosion even in harsh environments. With a working pressure of up to 300 bar (depending on diameter) and a safety factor of 4:1, it delivers reliable performance under heavy-duty conditions. For pulsating pressure, the maximum working pressure should be reduced by 50% to ensure long-term efficiency. The viton sealing provides excellent resistance to high temperatures and aggressive media, supporting an operating range from -20°C to +200°C. Designed for hydraulic power transmission with oils, as well as industrial use with water, steam, fuels, gases, and chemicals, this coupling ensures optimal flow with a pressure drop of just 3 bar, making it a versatile and high-performance choice for professionals seeking safety, reliability, and efficiency.
