Mastercool 63736-K Economy R134a/R1234yf Conversion Kit

Professional economy conversion kit to easily convert any R134a manifold gauge set to a R1234yf manifold gauge set. R1234yf is the new environmentally-friendly refrigerant standard (GWP less than 1) mandated for all new vehicles in Europe from 2017. Vehicles registered before 2017 typically use R-134a, while newer vehicles use R1234yf. This kit includes essential quick couplers and adapters for working with both refrigerant types, preventing cross-contamination. Cost-effective solution for shops servicing mixed vehicle fleets.

Key Features:

• Economy conversion kit
• Converts R134a manifold to R1234yf manifold
• High side R1234yf quick coupler (12 mm-F x 17 mm)
• Low side R1234yf quick coupler (12 mm-F x 14 mm)
• ACME thread adapter included
• Two R1234yf adapters (12mm-M x 14mm-F)
• Prevents cross-contamination
• Cost-effective solution
• Professional-grade quality

Kit Includes:

• 67434: High side R1234yf 12 mm-F x 17 mm quick coupler
• 67534: Low side R1234yf 12 mm-F x 14 mm quick coupler
• 83633: 1/2" ACME-M x 1/2" ACME-F LH thread adapter
• (2) 83735: 12mm-M x 14mm-F R1234yf adapters

About R1234yf vs R-134a:

• R1234yf: New environmental standard, GWP less than 1, post-2017 vehicles
• R-134a: Previous standard, GWP of 1,430, pre-2017 vehicles
• Not compatible - different service fittings prevent cross-contamination
• R1234yf uses 17 mm high side and 14 mm low side ports
• Illegal to put R-134a into R1234yf vehicles
• Similar cooling performance and efficiency

Specifications:

• Type: R134a/R1234yf conversion kit
• Refrigerants: R134a and R1234yf
• High Side Coupler: 12 mm-F x 17 mm quick coupler
• Low Side Coupler: 12 mm-F x 14 mm quick coupler
• Application: Automotive A/C service

Applications:

• Converting R134a manifold to R1234yf service
• Servicing R134a vehicles (typically pre-2017)
• Servicing R1234yf vehicles (typically post-2017)
• Mixed fleet automotive A/C service

Benefits:
