Pressure Gauge & Thermometers Accessories
A precision-engineered brass isolation valve for pressure gauges and instrumentation lines. Designed for non-corrosive applications, it provides smooth flow control and easy maintenance. Operating up to 16 bar and 93°C, it ensures safe and reliable pressure isolation. Available in ¼” and ½” BSP/NPT connections.
A protective fitting that stabilizes pressure readings and prevents gauge damage from pulsations or spikes. The porous mesh insert moderates flow, extending gauge service life. Manufactured in brass or stainless steel (304), with sizes from ¼” to ½” BSP/NPT, and pressure capacity up to 100 bar.
A DIN 16261 PN16 compliant isolation valve for pressure gauges, allowing easy venting or removal during service. Constructed from high-grade brass with optional vent hole, suitable for both BSP and NPT connections. Operates up to 16 bar and 50°C, ideal for HVAC and general industrial systems.
A circular-type syphon designed to protect gauges from steam or high-temperature media by cooling the process fluid before it reaches the instrument. Available in mild steel, brass, or stainless steel 304, with multiple BSP/NPT sizes and a maximum working pressure of 25 bar.
A U-shaped thermal protection device for pressure gauges in steam and hot fluid systems. Functions as a condensate barrier to prevent direct heat transfer. Offered in brass, mild steel, or stainless steel, rated for 25 bar, with a full range of BSP and NPT connection sizes.
A self-sealing test access point for temperature and pressure measurement in low-pressure HVAC systems. Constructed from brass with neoprene and EPDM sealing elements, it operates up to 35 bar and 125°C. Suitable for probes up to 4 mm diameter, available with ¼” and ½” BSPT connections and optional lagging extensions.
