Why Choose RCS:
-
Unmatched Quality Control:
Each RCS coupling undergoes an extensive multi-phase testing protocol that exceeds industry standards. From raw material selection to final assembly, we ensure that every component meets strict performance specifications. Unlike our competitors, we use cutting-edge testing technologies to simulate real-world pressure and temperature conditions, ensuring that our couplings perform optimally, even under extreme stress.
-
Precision Engineering:
RCS is the result of innovative
engineering designed specifically to address the common issues faced by
traditional refrigerant couplings. Through the integration of advanced
materials and sophisticated design methods, we've created a coupling
system that ensures maximum leak prevention, enhanced sealing
capability, and longer lifespan. This means fewer maintenance costs
and greater system efficiency for your operation. -
Robust 1500psi Rating:
When it comes to refrigerant couplings, strength and durability matter. RCS
leads the industry with an impressive 1500psi rating, offering the
highest pressure resistance in its class. This robust pressure rating ensures
that RCS couplings will perform in the most high-pressure applications,
providing unmatched reliability and minimizing the risk of leaks or failure.
Whether you're handling high-pressure systems or the toughest refrigerants, RCS guarantees superior performance and peace of mind. -
Built to Last:
With RCS, you're investing in a future-proof solution. Designed with
adaptability in mind, our couplings are engineered to work seamlessly with emerging refrigerants and evolving industry standards. The high-quality
materials and precise manufacturing processes used in RCS ensure that
these couplings are not only suitable for today's refrigerant systems but will
continue to provide reliable performance as industry requirements evolve.

Frequently Asked Questions
WHAT IS THE INTENDED APPLICATION FOR RCS FITTINGS?
RCS Mechanically attached fittings are high-pressure flame-less type fittings intended for use on refrigeration piping systems with all
refrigerants and refrigerant oils except Ammonia (R717) and Methyl Chloride (R40). Do not use for Refrigerants R717 or R40.
CAN YOU REMOVE AND REUSE RCS FITTINGS?
No. Once the fitting is pressed onto the tubing, the fitting is non-removable. If the fitting is deemed not visually acceptable prior to during, or after the installation, the fitting must be cut out from the piping system and a new one correctly reinstalled.
CAN THE RCS FITTINGS BE USED ON FLUIDS OTHER THAN REFRIGERANTS, SUCH AS WATER, MEDICAL GAS, OR COMPRESSED AIR?
No, the fittings should only be used on clean, dehydrated closed refrigerant piping systems.
WHAT IS THE PRESSURE RATING FOR RCS FITTINGS?
RCS fittings are ETL listed for a maximum working pressure of 1,500 psi. The fittings are tested and rated in accordance to UL-207
Standard for use in the USA and Canada.
DO YOU NEED TO DERATE THE WORKING PRESSURE OF THE INSTALLED TUBING?
The copper tube working pressure does not need to be de-rated to the annealed copper working pressure (required for brazed
copper piping systems). The working pressure of the installed system is equal to the working pressure raƟng of the tubing
(based on size, wall thickness, and temper) up to a maximum working pressure of 1,500 psi.
CAN RCS FITTINGS BE USED IN HAZARDOUS ENVIRONMENT?
No. RCS fiƫngs are intended for use on refrigeraƟon piping system and therefore required to be insulated to prevent from
moisture intrusion. All RSC fiƫngs installed outdoors or in humid environments require the installaƟon of a protecƟve heat
shrink, cold shrink, or other impervious covering material.
DO YOU NEED NITROGEN PURGE WHEN ASSEMBLING REFRIGERATION PIPING WITH RCS FITTINGS?
No. RCS fittings allow for the installation of refrigerant piping without the need for heat. Therefore, the tubing does not need
nitrogen purge (prevents copper oxide formation during brazing).
CAN RCS FITTINGS BE USED ON “SOFT” COPPER TUBING?
Yes, RCS fittings are suitable for use on annealed (O60), light drawn (H55), and general purpose drawn (H58) copper tubing. RCS fittings must utilize a tube support insert sized properly for the tube OD and wall thicknesses. Alternative tube support inserts must be used when RCS fittings are installed on annealed copper coil or pre-insulated line sets with tube wall thickness less than specified by
ASTM B280. Do not use on annealed copper sizes larger than 7/8” O.D.
HOW DO YOU ATTACH FLARE CONNECTIONS WITH RCS FITTINGS?
RCS offers “Flare Tube Kits” for precise and reliable means to connect flare end connections. This is a factory flared copper tube and RCS coupling, that requires the installer to use the flare nut furnished with the original equipment. The flare nut is NOT furnished as part of the RCS flare kit. Otherwise, if using annealed (O60) or “annealed” copper tube, the tubing can be field flared in the normal manner.
HOW DO YOU MAKE CHANGES OF DIRECTION (ELLS, OFFSET, ETC.)?
If the refrigerant piping is done using annealed (O60) or light drawn (H55) copper tube, the tubing can be field bent to any desired angle and connections made with RCS couplings. Do NOT bend general purpose drawn (H58) “hard” copper. Note: Use ONLY copper tube benders sized to precisely bend imperial size OD dimensions. Do NOT use conduit benders. For light drawn (H55) copper tube, do NOT
use “Press Bending” or “T-Bender” style benders. Refer to RCS detailed installation instructions for additional information.
CAN YOU PERFORM A BRAZE NEAR A FITTING?
Keep the temperature of the RCS fitting less than 250F (121C) by directing the flame away from the fitting, using a heat conductive paste and wrapping the fitting in a clean wet rag.
