Pristine purity and super fast freight delivery
I run an HVAC commercial service fleet in north Texas. Tested this cylinder on our manifold and the pressure-temperature curve was dead accurate. Factory shrink seal was 100% intact. Zero contaminants or acid. Outstanding commercial supplier.
Been using Groundmark for our summer peak season orders. The 25lb cylinders arrive in heavy-duty shipping cartons with no dented collars or valves. Clean subcooling and superheat numbers every time.
Customer was having chronic compressor high-head issues from recycled gas bought elsewhere. Flushed the system and charged with Groundmark R-410A. Running whisper quiet and pulling 18 degrees delta T.
Received our cylinders within 2 business days of ordering. Box packaging is first class with hazmat labeling clearly displayed. Will definitely be keeping Groundmark on our primary vendor list.
Is this 100% virgin refrigerant or reclaimed/recycled gas?
Every refrigerant cylinder supplied by Groundmark is strictly 100% virgin-grade gas certified to AHRI-700 standards. We never sell reclaimed, recovered, or recycled gas. You receive factory-fresh, laboratory-tested purity with every cylinder.
What valve fitting is installed on this cylinder?
The cylinder comes equipped with a standard 1/4" Male Flare (SAE) brass outlet connection with an internal valve core and resealable thumb-knob. It connects directly to standard HVAC service charging manifolds and charging hoses.
How is hazardous materials freight handled?
Refrigerant cylinders are classified under DOT regulations for compressed non-flammable gas. They are packaged in heavy-duty double-wall reinforced cartons and shipped via certified ground freight carriers directly from our Dallas, TX warehouse.
What lubricant oil is compatible with this refrigerant?
R-134a is compatible with PAG and POE oils; R-410A and R-404A utilize POE synthetic lubricants; R-422B is drop-in compatible with MO (mineral), AB, and POE oils. Always check your compressor manufacturer specifications.
