These used HP120 steel scuba cylinders are a dependable and cost-effective option for divers looking for quality steel tanks with verified testing already completed. HP120 tanks are well known for their durability, favorable buoyancy characteristics, and long service life, making them popular with recreational divers, technical divers, and public safety dive teams.

All HP120 tanks in this listing include a recent hydrostatic test and visual inspection and are equipped with a 300 bar DIN Valve. These cylinders are sourced from customer trade-ins, excess shop inventory, and store-owned tanks, and each tank is individually evaluated prior to being listed.
