Coil SyphonsExtend the life of your pressure instruments with our durable coil siphons. Designed to act as a protective barrier, coil siphons help cool process media and prevent direct exposure of hot gases or liquids to pressure gauges, switches, and transmitters. This ensures more accurate readings and longer instrument service life. Available in a range of materials, sizes, and pressure ratings, our coil siphons are ideal for use in steam systems, boilers, chemical processing, and other high-temperature applications. Their coiled design dissipates heat efficiently while providing a reliable seal between process media and sensitive instruments. Built with rugged construction and trusted-brand quality, our coil siphons deliver dependable performance and are an essential accessory for protecting pressure measurement equipment in demanding environments.
Gauge Cock ValvesImprove safety and extend the life of your instruments with our dependable gauge cock valves. Designed to provide easy isolation of pressure gauges and switches, these valves allow for quick removal, inspection, or replacement without disrupting your system. Available in a variety of materials, pressure ratings, and connection types, our gauge cock valves are commonly used in boilers, steam systems, chemical processing, and industrial equipment. They provide a secure shutoff while helping protect sensitive instruments from overpressure, damage, or unnecessary wear. With rugged construction, simple operation, and trusted-brand reliability, our gauge cock valves deliver long-lasting performance and peace of mind in demanding applications.
Pressure SnubberProtect your instruments and ensure accurate readings with our durable pressure snubbers. Engineered to reduce pulsations, spikes, and rapid pressure fluctuations, snubbers safeguard gauges, switches, and transmitters from damage while delivering smoother, more reliable measurements. Our selection includes brass, stainless steel, and porous metal snubbers, available in a variety of connection types, pressure ratings, and orifice sizes to match your application needs. Ideal for pumps, compressors, hydraulic systems, and industrial process equipment, pressure snubbers are a simple, cost-effective way to improve instrument performance. With rugged construction and trusted-brand quality, our pressure snubbers provide long-lasting protection, extended instrument life, and dependable accuracy in demanding environments.
