SURIEEN R134A Recharge Hose Kit with BPV31 Bullet Piercing Tap, 19" Multi-Scale Gauge & 1/4" Adapter

SURIEEN R134A AC Recharge Hose Kit pairs a 19-inch, multi-scale gauge hose with a BPV31 3-in-1 bullet piercing tap and adapters to safely top up R134a, R12 and R22 systems.

This compact kit combines a clear, 19" charging hose and a 2.75" gauge calibrated for R134a, R12 and R22 with a BPV31 bullet piercing valve and adapters so you can connect a refrigerant can to most vehicle and appliance service ports. It’s designed for straightforward, low-profile installation and includes a 1/4" adapter for mini-split and refrigeration fittings. Materials and manufacturing focus on durability and leak resistance, and the package includes a hex key and spare adapters for immediate use.

How does the gauge work for different refrigerants?

The 2.75" analog gauge on the hose shows pressure scales for R134a, R12 and R22 so you can read approximate system pressures without swapping tools. It’s calibrated to guide charging and troubleshooting but should be used alongside recommended service procedures and safety practices.

• Three printed pressure scales: R134a, R12, R22 for direct reading.
• Clear face with needle indicator for quick visual checks.
• Built-in 1/4" end compatible with R12/22/502 fittings when adapting service ports.

What makes the BPV31 piercing valve useful and safe?

The BPV31 is a 3-in-1 bullet piercing tap valve that fits three common tubing sizes (1/4", 5/16", 3/8") and includes two adapters plus a hex key for controlled installation. It’s engineered to avoid accidental refrigerant discharge by using a threaded piercing mechanism that stays sealed until fully engaged.

• Three-size compatibility reduces the need for extra valves.
• Hex key control gives steady, measured piercing to limit leaks.
• Includes adapters to fit mini-splits, HVAC and refrigeration lines.

How easy is the kit to install and use?

This kit is built for straightforward, space-efficient installation: attach the correct adapter, position the piercing valve, tighten with the provided hex key and connect the hose to the refrigerant can. The 19" hose provides reach without excess slack, and the 1/4" adapter lets you work with most service port threads commonly found in automotive and light refrigeration tasks.

• Simple mechanical installation—no specialized tools beyond the included hex key.
• Compact hose length for reachable connections in tight engine bays.
• Replacement-friendly components and clear adapter choices.

What materials and warranty cover the kit?

Components are made from durable, service-grade materials and undergo manufacturer testing to minimize degradation under typical use. SURIEEN backs the kit with a 12-month warranty; if the part fails under normal use within that period, you can request replacement or refund through customer service.

• Durable hose and metal valve construction for repeated use.
• Manufacturer-tested parts to reduce accidental discharge risks.
• 12-month limited warranty with customer support for defects.

Who is this for: Technicians, DIYers and HVAC hobbyists who need a compact, adaptable R134a charging solution for automotive or light refrigeration tasks will find this SURIEEN kit practical. It’s suited for those who want multi-refrigerant gauge readings, a versatile piercing valve for different tube sizes, and a simple installation process without investing in larger manifold sets. Not intended as a substitute for professional service on complex systems or for refrigerants outside the listed types.
