Propane Parts + Floats & Reliefs
Gas Cylinder Source provides a specialized range of propane parts, floats, and pressure relief components designed for use in propane cylinders and propane cylinder valves where overfill prevention, pressure management, and regulatory compliance are critical. This category includes float assemblies, overfill prevention device (OPD) components, pressure relief valves, relief plugs, and related internal safety parts, not propane cylinders themselves.

Propane floats and relief devices play a vital role in preventing overfilling, managing internal pressure, and protecting cylinders from hazardous conditions. Float mechanisms in propane cylinders and valves control fill levels, while pressure relief components are engineered to safely vent gas if internal pressure exceeds design limits. Together, these components support safe filling, storage, transport, and use of propane.
Selecting the correct propane part depends on cylinder size, valve design, pressure rating, application type, and applicable safety standards. Gas Cylinder Source supports cylinder manufacturers, refurbishers, propane marketers, OEMs, and certified service technicians who require DOT-compliant, CGA-aligned components for inspection-driven maintenance, valve rebuilding, or cylinder requalification.
All propane parts, floats, and relief devices are intended for professional installation and servicing only, in accordance with DOT regulations, NFPA 58, CGA standards, and manufacturer specifications. Proper component selection is essential for life safety and inspection readiness.
FREQUENTLY ASKED QUESTIONS
What are propane floats and relief devices used for?
Propane floats and relief devices are used to control fill levels and manage excess pressure inside propane cylinders.
Float mechanisms help prevent overfilling, while relief devices protect the cylinder from dangerous pressure buildup. Both are essential safety components.
They support safe propane handling and compliance.
Are these parts for propane cylinders or propane systems?
These parts are designed specifically for propane cylinders and propane cylinder valves.
They are internal or valve-mounted components, not downstream system parts. Their function is tied directly to cylinder safety.
This distinction is critical for correct selection.
What is a propane float assembly?
A propane float assembly is a mechanical component that rises as liquid propane fills.
It helps signal or limit the fill level to prevent overfilling. Float systems are commonly associated with OPD-equipped valves.
They are required for modern propane cylinders.
What does a propane pressure relief device do?
A propane pressure relief device safely vents propane if internal pressure exceeds safe limits.
This prevents cylinder rupture due to overheating or overpressure. Relief devices activate automatically under defined conditions.
They are a last-resort safety feature.
Are propane floats and reliefs required by regulation?
Yes, propane floats and pressure relief devices are required by regulation.
DOT, NFPA 58, and CGA standards mandate their use in approved propane cylinders. Compliance is legally required.
Non-compliant cylinders cannot be placed into service.
Who installs propane floats and relief devices?
Propane floats and relief devices are installed by certified cylinder manufacturers, refurbishers, or licensed propane service professionals.
Installation requires specialized tools and procedures. Improper installation can result in serious safety hazards.
Professional installation is mandatory.
Can propane floats and relief parts be reused?
Some propane parts may be reused if they pass inspection and meet current standards.
However, worn, damaged, or outdated components must be replaced. Reuse decisions follow strict regulatory criteria.
Safety dictates replacement thresholds.
Do propane relief devices control pressure during normal use?
No, propane relief devices do not regulate pressure during normal operation.
They remain closed unless pressure exceeds design limits. Pressure regulation occurs downstream using regulators.
Their role is emergency protection.
Are all propane floats and reliefs the same?
No, propane floats and relief devices vary by cylinder size, valve design, and pressure rating.
Using incorrect components can compromise safety and compliance. Specifications must match the cylinder and valve.
Compatibility is essential.
Who should buy propane parts, floats, and reliefs from Gas Cylinder Source?
These components are intended for professional users in the propane industry.
Typical buyers include cylinder refurbishers, propane distributors, OEMs, and certified service technicians. Consumer use is not appropriate.
Gas Cylinder Source supports compliance-driven propane operations.
