Product Overview
The Samson Form Standard Stem Packing (Part Numbers 1120-2402 and 1120-2401) is a precision-engineered sealing replacement assembly designed for industrial linear globe and control valves. Manufactured by Samson AG, this spring-loaded V-ring packing system provides reliable dynamic stem sealing across standard valve configurations, including the flagship Samson Type 3241 and Type 3251 series. It maintains positive fluid containment along the moving valve stem while preventing fugitive emissions into the surrounding plant atmosphere.
Engineered with high-grade virgin PTFE and carbon-filled PTFE V-rings energized by an internal corrosion-resistant stainless steel compression spring, this packing assembly delivers consistent sealing force without requiring manual gland readjustment. The low friction coefficient of PTFE minimizes mechanical stem hysteresis, ensuring fast, accurate valve throttling and extended service life. The assembly is widely used across chemical processing plants, oil and gas refining, petrochemical facilities, industrial steam networks, and automated utility piping systems.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
