FASTLOCK A3–A2L (39000) is the fitting developed by OLAB for professional refrigeration systems using A3–A2L refrigerants, fully compliant with the latest environmental regulations. Featuring the patented Fast Lock A3–A2L connection system, it enables quick, secure, and completely weld-free assembly. This drastically reduces installation time and cost, while ensuring a permanent mechanical seal — without the need for special tools or qualified personnel.

The body and components are made of high-precision yellow brass, while the reinforcement bush is manufactured in AISI 303 stainless steel and includes an AST groove (Anti-Slip Tube).
Combined with the deformable ogive, this ensures the tube is securely retained inside the fitting, even under extreme pressure cycles. Every critical sealing point is protected by HNBR O-Rings that are 100% PFAS-FREE and certified by OLAB, ensuring flawless tightness even in severe thermal and chemical conditions.

The structure is designed for easy assembly and disassembly, simplifying maintenance operations and enhancing system safety.
Tested up to 52 bar (754 psi) and operating in a temperature range of –40°C to +150°C (–40°F to +302°F), FASTLOCK A3–A2L (39000) is UL 207 certified and classified among OLAB’s 100% PFAS-FREE COMPONENTS, delivering a sustainable, reliable, and advanced solution for HVAC-R professionals.  

Technical features:

  • Yellow brass body e and component
  • Stainless steel reinforcement bush AISI 303
  • O.R. in OLAB Certified 100% PFAS-FREE HNBR 
  • Designed for professional A3-A2L refrigeration systems

COMPATIBLE A3–A2L REFRIGERANT GASES

HFC, HFO, and HFO/HFC blends: R404A, R407C, R410A, R507, R32, R134a (up to +125°C / 257°F).
HFO and HFO/HFC blends: R1234ze, R448A, R449A, R450A, R452A, R1234yf.

Products equipped with HNBR seals must not be installed on systems using HCFCs (R22) or any refrigerants mixed with mineral oils or alkylbenzene lubricants.

Our HNBR compound seals have been specifically designed and manufactured for compatibility with A3 and A2L refrigerant gases (as defined in ASHRAE Standard 34). However, due to the countless variables involved in real-world applications—such as pressure, temperature, and mixing ratios—an application-specific validation on the system is always required.

FAST LOCK A3–A2L CONNECTION SYSTEM
Completely eliminates the need for welding, reducing installation time and cost while ensuring a perfect seal.


SAFE

Eliminates hazardous welding operations. The tube is inserted directly into the OLAB Fast Lock connection.


HNBR 100% PFAS-FREE O-RINGS CERTIFIED BY OLAB

Perfect sealing at every potential leakage point.


RELIABLE

The deformation of the ogive, combined with the AST groove on the reinforcement bush, ensures secure mechanical retention of the tube within the fitting body.


EASY

Extremely simplified assembly and disassembly of components.
