UP AQUA A-171-S CO2 Regulator (Sliver)

Description

Adopt high-pressure structure design, many parts, high production cost, but the parts are independent and easy to maintain.

The high pressure resistant part of Teflon gasket (PTFE) is used for better air tightness and durability.

In a separate design, the high-pressure gas thrust does not affect the internal parts.

Usage:

UP omnibus regulator designed to easily connect. Simply tighten the regulator clockwise direction by hand, without the need of any tool.
To take off the nut or change the nut, the regulator can be used on disposable cartridge or different caliber of CO2 bottle.

The UP Aqua A-171-S CO2 regulator for planted tanks

A solid regulator is where a reliable CO2 setup begins, and the A-171-S uses a high-pressure design with a PTFE seal for good airtightness and durability over the long haul. The separated construction keeps high-pressure thrust off the internal parts, and the modular layout means individual pieces can be serviced rather than scrapping the whole unit. It connects by hand-tightening, so you can fit it without tools and adapt it to disposable cartridges or larger refillable bottles.

For Singapore planted-tank keepers, the bottle question matters: disposable cartridges suit small nano tanks, while a refillable cylinder is far more economical for a larger high-tech setup, and local refills are readily available. Whatever you run, pair the regulator with a solenoid and timer so CO2 shuts off at night, fit a check valve, and confirm your level with a drop checker rather than guessing from the bubble count alone.

See the rest under CO2 systems; our planted-tank CO2 system guide and aquarium CO2 guide explain how the parts fit together.
