Category: A1-A2L-A3 SPECIALIST
Notes:
SAFELOCK (K10042) is the access fitting developed by
OLAB for professional A3–A2L refrigeration systems. It features the Fast
Lock A3–A2L connection system, which completely eliminates the need for
welding, reducing installation time and cost while ensuring a secure, leak-free
joint without requiring specialized tools or personnel.
The component is equipped with a hexagonal cap
designed for use with a standard wrench. This configuration allows safe
recharging of the system and, more importantly, guarantees perfect resealing
thanks to the dual HNBR seal integrated into the cap itself.
All sealing elements are made of HNBR 100% PFAS-FREE,
certified by OLAB, ensuring maximum chemical compatibility with A3–A2L
refrigerants and long-lasting sealing performance under thermal and pressure
stress.
Reliability is further enhanced by the mechanical locking
system: as the nut is tightened, the ogive deforms, and the AST
groove on the stainless steel reinforcement bush ensures secure retention
of the tube inside the fitting body—even during intense pressure cycles.
Assembly and disassembly are quick and simple,
entirely mechanical, and free of thermal stress, preserving the integrity of
both the fitting and sealing components.
Each unit is 100% helium tested in a dedicated
facility. Laser-marked date and serial number certify that the fitting
has passed the test and allow lifetime traceability of performance data.
SAFELOCK (K10042) is rated for 52 bar (754 psi) and
operates within a temperature range of –40°C to +150°C (–40°F to +302°F).
As part of OLAB’s 100% PFAS-FREE COMPONENTS range, and UL 207
certified, it represents a new benchmark in safety, sustainability, and
technical reliability for modern refrigeration systems.
Technical features:
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.
HC: R290, R600, R600a.
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
Removes hazardous welding operations. The tube is inserted directly into the
OLAB Fast Lock connection.
HNBR
O-RINGS 100% PFAS-FREE CERTIFIED BY OLAB
Perfect sealing at every potential leakage point.
OLAB
SOLUTION
The only charging port with a cap featuring a dual-seal system.
HI-PERFORMANCE
The hexagonal shape of the cap allows the charging port to be closed using a
standard wrench. This enables the technician to recharge the system and — most
importantly — to reseal it perfectly without any leaks, thanks to the
double-seal configuration.
RELIABLE
The deformation of the ogive, combined with the AST groove on the reinforcement
bush, ensures secure retention of the tube inside the fitting body.
EASY
Component assembly and disassembly are extremely simple and fast.
100%
HELIUM TESTED
Each component is individually tested in an advanced helium system.
Laser-marked date and serial number certify the successful test and ensure
lifetime traceability of performance data.
