Contact Us ↗ZPUSH Taiwan Refrigerant connection technology
Flame-free push-to-connect fittings for refrigerant copper tubing.Prepare the tube, then push it into place.
Please confirm the model, refrigerant and installation conditions with us.
WHY ZPUSH / INSTALLATION BENEFITS
From preparation to connection,
skip brazing and flaring at the push-fit end.
Push-fit connections require no brazing, reducing exposure to open flames and high temperatures. This helps with planning work in areas with hot-work restrictions, building retrofits and crowded equipment rooms.
Site permits and local work rules still apply.The push-fit end connects directly to properly prepared copper tubing. Mark the insertion depth with a gauge, push the tube fully into place and check the connection.
*Applies to the ZPUSH push-fit end. Equipment-side connections depend on the selected fitting.No bulky brazing equipment to carry and no brazed joint to cool. Connect after preparing the tube ends, making it a practical option for repairs, small installations and confined spaces.
Installation time varies with tube size, site conditions and experience.The connection process produces no brazing oxide scale and reduces reliance on filler metal, flame and brazing skills. Tube cleanliness and connection checks remain essential.
Pressure holding, leak testing and evacuation are still required to the applicable specifications.

No brazing or on-site flaring at the push-fit end. Choose from straight couplings, elbows, reducers and service fittings.
For existing 45° flare connections. A corrugated copper core and pre-applied coating help improve the seal.
QUALITY, WITH EVIDENCE
From third-party reports to factory testing,
review the evidence behind the product.
The catalog includes UL Certificates of Compliance. Representative samples of the listed refrigerant fittings were evaluated to UL 207 and Canadian standard CSA C22.2 No. 140-3.
Applies to the straight coupling and elbow models listed in the certificates. These are component certifications, not certifications of complete HVAC systems.
The SGS report records tests on specified ZPUSH samples to ISO 14903:2017, including tightness, pressure/temperature/vibration, operation simulation, freezing and vacuum tests.
The SGS confirmation letter records no leakage when samples were held at 250 bar for one minute. This is a test condition, not a permissible working pressure.
The catalog includes an SGS RoHS report. The specified samples received a Pass result for the listed restricted substances, including lead, cadmium and mercury.
Results apply to the samples and test scope stated in the report. Ask us for the documentation relevant to your product selection.
Based on documents included in the supplied catalog: UL certificates dated August 26, 2025; SGS performance report September 9, 2024; pressure test letter September 18, 2024; RoHS report May 28, 2024. Confirm certification coverage against the model numbers and product markings.
INSIDE THE FACTORY
The September 24, 2026 catalog lists 10 production quality checks and 13 product performance tests covering sealing, pressure resistance, mechanical loads and environmental exposure after assembly.
See the factory visit ↓Working pressure, five times working pressure, burst, low-pressure tightness and vacuum tests assess sealing under different conditions.
Tensile tests with and without pressure, maximum bending and repeated bending examine connection integrity under mechanical loads.
The catalog lists two million vibration cycles and 250,000 pressure impulse cycles to assess performance under repeated loading.
The catalog lists 1,000 hours of neutral salt spray and 24 hours of ammonia exposure testing to check for corrosion and cracks.
This section describes factory internal testing; it does not mean that every test was performed by SGS. Cycle counts do not constitute a service-life guarantee.

YOUR LOCAL CONNECTION
Taiwan HVACR Co., Ltd.
From push-fit fittings to sealing gaskets, we help you confirm sizes, refrigerants and application requirements.
No. You still need to cut, round, deburr inside and outside, clean and inspect the tube, then mark the insertion depth. Flame-free connections still require proper tube preparation.
Confirm compatibility for the specific model with the manufacturer. Share the refrigerant, tube outside diameter and system operating conditions so we can help check your selection.
The ZPUSH push-fit end connects to prepared copper tubing without on-site flaring. FlareGasket fits an existing 45° flare connection. They serve different purposes.
