Our Refrigerant Cap for canisters with valve stems and threaded outlets has been designed to provide the perfect protection while the canisters are being stored in your workshop or being carried to and from sites. Impact, contamination of threads, collecting of debris and worst of all accidental release while in your workshop of aerosol held in the valve stem of the canister is prevented by our protective cap.
Bluefire Refrigerant Caps are made from high-impact, chemically resistant polymers, offering great rigidity and environmental stability. A variety of cap sizes and thread patterns are available for use with single-layer and double-layer refrigerant aerosol valves. Manufactured on fully automated, high-precision assembly lines, each cap is designed to deliver a consistent snap-fit or thread-on torque, ensuring the same high standard of performance from batch to batch. This makes them ideal for use in automated filling and packaging lines.

Multi-Size Versatility: Available in a variety of sizes including 7/16”-28, 1/2”-16 and Universal aerosol valve neck sizes to meet worldwide market requirements for packaging of consumer products.
Sturdy & Durable Material Build: This Industrial plug is Formulated from the raw polymer materials that resist cracking, brittle fracture and degradation due to chemical exposure, cold temperatures and rough shipping conditions.
Tamper Evident & Leakage Safeguard: Our safeguard system works with EN417-compliant valve assemblies. In transport it prevents accidental stem activation. Secondary seal integrity of refrigerant cans is thus protected.
Fully Automated Manufacturing Consistency: High speed automated production lines that do not have any human error, so produce components with consistent dimensional tolerances, accurate thread forms and with a consistent cap retention force.
Dust & Moisture Isolation: The form-fitting seal perimeter prevents dust, sand, moisture, and road grime from entering into the valve orifices before the service hose is attached.
Automotive AC Recharge Canisters: A stem protection device for the DIY user who buys R134a or R1234yf recharge cans for their cars’ air conditioning systems in retail auto stores and professional auto supply stores.
HVAC & Commercial Refrigeration Supplies: Portable refrigerant canisters (R600a, R290, R22 replacement gas) for technician’s use while working in the field.
Industrial Gas Packaging & Storage. A number of technical aerosol gases and also specialized blowtorch fuel cans require safe storage and also also suitable packaging for transport by international sea freight.
The Bluefire refrigerant cap is engineered to lock securely onto standard aerosol mounting cups (25.4mm / 1-inch) and specialized threaded valve bodies. We offer complete OEM/ODM customization services, including custom color-coding (matching specific refrigerant gas color standards like blue, green, or red), embossed corporate logos, tamper-evident seals, and specialized bulk packaging for automated cap sorting equipment.
Q1: What sizes are available for the Bluefire refrigerant cap?
A: What size of chimney connector will fit on standard aerosol valve stems? We have several sizes of connectors designed to fit on valve stems. These include sizes that fit on 7/16’-28 UNEF threads, on 1/2’-16 ACME threads, and on general 1” mounting cup rim dimensions.
Q2: How does the cap contribute to EN417 compliance?
A: In addition to containing pressurized gas, the outer cap of the valve is a secondary mechanical part and thus a protection for external forces on the stem of the valve. Complete canister packages can be supplied for transport in conformity with EN417 safety requirements.
Q3: Can the caps for these cans be color coded for the different types of refrigerant in the cans?
A: Yes. We offer custom color molding for your product, such as light blue for R134a or rose for R410A equivalents. The custom colored molding will assist the distributors to identify your product safely and efficiently.
