The best thing about Ardes O-Ring syringes is their incredible durability, but the silicone o-rings don't last forever!
Henry's now carries these replacement silicone O-Rings in four sizes: 10 mL, 20 mL, 30 mL, and 50 mL. The rings are all sold individually and work with both the standard syringes and the locking syringes.
Note: Ardes O-rings are uniquely shaped and will not work as replacement o-rings for other brands of syringes!
