Discover our high-quality pressure gauge, specifically designed for measuring outlet pressure. This product features a 1/4" male threaded back connection, ensuring a reliable and secure fit. Perfect for both professional and DIY applications, our pressure gauge is an essential tool for accurately monitoring pressure levels. Enhance your projects with this durable and efficient instrument.

The FSSCDF Forward Acting Rupture Discs feature precision micro-scored sections that open in controlled petals, using four, six, or more radial score lines to ensure a clean, reliable opening while minimising the risk of petal separation. This design makes them particularly well suited for high burst pressure applications and for systems operating under cycling or pulsating conditions with gases or liquids, without compromising safety margins.

These discs respond to overpressure within milliseconds, opening fully without fragmentation, and are ideal for protecting safety relief valves. They support an operating-to-burst pressure ratio of up to 85%, offer excellent corrosion resistance, and can be further enhanced with an optional PTFE lining. In many applications, the discs can also withstand full vacuum conditions without additional supports, providing flexible installation options.
