Buying Guide
What cylinder size should I choose?
24-gram cartridges provide a compact option with sufficient buoyancy for standard inflatables. Some vests may require larger 33-gram cylinders for faster inflation or higher buoyancy. Check your vest’s specification label or user manual for the recommended cylinder size.
Is my vest compatible with 1/2-inch threading?
Most rearming cartridges use a 1/2″ thread. Confirm the thread size on your vest’s inflator valve before purchasing. Using an incorrect thread can prevent proper sealing and inflation.
Should I buy a single cartridge or a multi-pack?
A single cartridge works for routine maintenance or replacement, while a multi-pack reduces the need for frequent reorders and is ideal for groups, families, or emergency kits. Consider the number of inflatables you own and how quickly you replace spent cartridges.
Are there model-specific requirements?
Some manufacturers require cartridges designed for their models (for example Onyx A/M or A-33 IN-SIGHT). Using a non-compatible cartridge may lead to unreliable inflation. Always verify model compatibility in product descriptions or the manufacturer’s guidelines.
What are common installation cautions?
Ensure the vest is not stored in extreme temperatures before replacing a cartridge. Tighten the cartridge firmly but avoid overtightening, which can damage threads. Inspect o-rings or seals for wear and replace if there are signs of damage.
What about spare parts and maintenance?
Having a spare cartridge on hand is prudent for outdoor enthusiasts. Regularly inspect your life jacket and rearming kit for corrosion or leaks. Store cartridges in a cool, dry place away from direct sunlight.
