Single-Stage Regulators
Browse the complete GasRegulators range — single-stage, two-stage, high-pressure, NEVOC, medical and gas-specific regulators for argon, CO₂, oxygen, acetylene, nitrogen, helium and propane. Every regulator is held in UK stock with same-day dispatch, and our technical team can help you specify the right unit for your application.
Single-stage regulators reduce cylinder pressure to working pressure in one step, making them a straightforward, cost-effective choice for MIG, TIG and cutting work where a small drift in outlet pressure as the cylinder empties is acceptable.
