Ketofa R1234YF Refrigerant Charge Hose Kit with Gauge – LH 1/2 ACME Tap & Low Side Adapter

Efficient, Safe Refrigerant Charging with Ketofa

The Ketofa R1234YF Refrigerant Charge Hose Kit is designed to help you add refrigerant to R-1234YF systems with a blend of precision and control. Built for compatibility with LH sealed cans, this kit focuses on steady flow, clear readings, and safe operation, so you can work with confidence in a home or small shop setting.

Designed with practical, real‑world use in mind, the system combines a 200 PSI gauge, a high‑strength hose, and a dedicated low‑side adapter. The left‑hand thread 1/2 ACME connection ensures a secure fit, while the 14 mm low‑side adapter aligns with the standard hardware used for R‑1234YF can charging. The result is a streamlined setup that helps you monitor charge levels as you go, reducing guesswork and facilitating a smoother recharge process.

Key Benefits at a Glance

• Compatibility with R‑1234YF LH sealed cans: Not designed for R‑134A or self‑sealing cans, ensuring appropriate use with compatible cylinders.
• Two secure connections: Left‑hand thread – 1/2 ACME‑LH and a dedicated R‑1234YF low‑side adapter for proper alignment.
• Built‑in safety valve: Helps minimize accidental venting during setup and operation.
• Clear pressure visibility: A 200 PSI gauge provides easy monitoring while charging.
• Robust, high‑pressure hose: Designed to withstand pipe pressures from 600 to 3000 PSI for reliable performance.
• Comprehensive dimensions: Total length 15.4 inches with a bottle opener thread of 1/2 inch and a 17.6 cm adapter head for flexible setup.

Usage is straightforward: connect to LH sealed cans (R‑1234YF only), monitor the low‑side pressure as you add refrigerant, and adjust as needed to avoid overfilling. The color‑coded low‑side gauge helps you interpret readings at a glance, supporting careful, measured charging. This kit provides options for a controlled transfer without making bold claims about outcomes, so you can assess results based on your own system and conditions.

Usage Tips & Safety Considerations

• Verify can type: Ensure you are using an R‑1234YF LH sealed can—do not use R‑1234YF self‑sealing or R134A cans.
• Monitor during charging: Use the gauge to track low‑side pressure and adjust the amount added accordingly.
• Inspect connections: Confirm a snug fit on both the LH thread and the low‑side adapter before opening the can.
• Safety first: Keep the system in a well‑ventilated area and follow standard refrigerant handling practices. Do not rely on this kit for guarantees; use it as a precise tool for charging with observed measurements.
