Boltigen R1234yf to R134a Adapter Kit — Brass High & Low Side Conversion, Built‑in Valve & Seals

Many workshops and DIYers still use R134a charging equipment while newer cars require the low‑pressure R1234yf fittings. This Boltigen adapter set provides a mechanical bridge between those systems: solid brass adapters, builtin seals and a simple knurled design let you attach R134a quick couplers to R1234yf service ports safely and quickly. The set includes adapters for both high and low service ports and is intended as a conversion accessory that must be used with R134a quick couplers—not as a standalone fitting.

How does this adapter let me use R134a tools on R1234yf systems?

The adapters mechanically adapt the different thread and valve geometry so a standard R134a quick coupler will latch onto an R1234yf service port. They include internal O‑rings, lock balls and a valve core to establish a sealed, serviceable connection so refrigerant fill or recovery tools can operate as if they were connected to a native R134a port.

• Converts service port interface—high and low side adapters included.
• Built‑in green O‑rings and five locking balls for secure seal.
• Valve core integrated to allow controlled charge and recovery.

Are these adapters durable and safe for repeated shop use?

Boltigen builds the adapters from solid brass for corrosion resistance and long life under repeated coupling cycles. The knurled outer surface helps technicians install and remove the adapter quickly with one hand, while the internal sealing components maintain a hermetic connection during charging operations.

• Solid brass construction resists wear and corrosion.
• Knurled body for fast, secure hand tightening and removal.
• Replaceable O‑ring and valve core design reduces leakage risk.

What are the setup and usage limits I should know?

This conversion kit is strictly a mechanical adapter and must be paired with an R134a quick coupler—the adapters alone do not replace service valves or hoses. They are intended for charging, service and testing when using compatible refrigerant handling equipment; always follow vehicle and refrigerant manufacturer guidelines for pressure, refrigerant type and safety protocols.

• Must be used with R134a quick coupler; not a standalone charging solution.
• Follow manufacturer procedures for refrigerant types and pressures.
• Inspect O‑rings and seals before each use; replace if damaged.

What support and warranty does Boltigen provide?

Boltigen offers a six‑month warranty on the adapter kit and provides around‑the‑clock customer support for troubleshooting and replacement requests. If you encounter fitment or sealing issues, contact Boltigen customer service first for guidance and warranty options.

• 6‑month warranty covers defects under normal use.
• 24/7 customer support for fitment and performance questions.
• Spare parts guidance available for seals and valve cores.

Who is this for: This adapter kit is aimed at professional mechanics, independent A/C shops and informed DIYers who already own R134a charging equipment but need to service R1234yf‑equipped vehicles. It’s a practical, mechanical conversion tool for bridging tooling differences—ideal when you require a reliable seal, quick connect/disconnect capability, and durable hardware for repeated shop use.
