SVS Series oxygen cylinder post-valve sleeves protect the delicate valves of oxygen cylinders. The sleeves slip easily over the valve and lock into place. Once the sleeve is applied it can only be removed by using the tear-tab. This tear-tab feature provides a tamper/use evident seal ensuring the tank delivered is full and free of contamination.

• SVS-1 is designed for valves that don't include a washer.
• The SVS-2W does accommodate the washer. It slips easily over the cylinder and its elasticity provides a snug fit ensuring it stays on the tank during transit. The netting buffers the tank and keeps it from being scratched and dented during shipment.
• The SVS-500 is a smaller version than the SVS-1 and SVS-2W. Its offers the same lock-in feature and tamper evidence, but has a reduced size covering less of the valve.
• SVS Series sleeves are patented
