Uniweld RHP800 Nitrogen Regulator – 0–800 PSI Single-Stage Brass Gauge (CGA 580)

The Uniweld RHP800 is a professional-grade single-stage nitrogen regulator designed for accurate gas delivery from 0–800 PSI. Its brass piston-and-diaphragm construction ensures durability and precision, even under heavy usage. Equipped with large 2″ gauges (up to 4,000 PSI on inlet, 1,000 PSI on outlet), both with protective rubber boots, and fitted with a stainless-teel-adjust screw and T-handle that resist galling, this regulator offers reliable performance for purging, pressure testing, and charging refrigeration systems.

The unit includes a self-reseating relief valve (not for downstream protection), a CGA 580 inlet, and a ¼″ male flare outlet. Approved for nitrogen and with optional adapters for CO₂, it supports a range of HVAC and refrigeration supplies. Crafted without HCFCs, this regulator is rugged, accurate, and backed by a 2-year warranty, ideal for technicians and shop use.
