Fieldpiece HR3B Ball Valve Refrigerant Charging Hose Set 3-Pack 5ft 1/4in A2L For Sale

SHEVAPRIME · HVAC & Automotive Tools · Hand Tools · Test Gear · Fast US Shipping FIELDPIECE HR3B 1/4" Ball Valve Refrigerant Hose Set | 3-Pack | 5 ft | A2L Compatible Model: HR3B | 3 Hoses | 800 PSI Working | 4000 PSI Burst | Condition: New Ball valves at the hose end — that's the whole point. Shut off flow right where you're working instead of venting refrigerant every time you connect or disconnect. Less loss, less mess, better control. And with A2L compatibility, these are ready for R-454B, R-32 and the rest of the low-GWP refrigerants replacing R-410A. Why You'll Like It ✔Ball valves at the hose end — precise shutoff that cuts refrigerant venting during connect and disconnect ✔A2L compatible — works with next-generation low-GWP refrigerants as well as standard ones ✔800 PSI working / 4000 PSI burst — a 5:1 safety margin for demanding service work ✔Permeation barrier meeting SAE J2196 — refrigerant stays in the hose instead of seeping through the wall ✔Full-ring triple crimp construction resists pull-out at the fitting — the failure point on cheap hoses ✔Four-layer build for durability in real field conditions ✔Interchangeable color tags included — mark red, yellow and blue for instant identification on a crowded job ✔5 ft length — easier to manage in tight mechanical rooms than 6 ft hoses ✔Standard 1/4" × 1/4" fittings — drop straight onto your existing manifold What's Included •(3) 1/4" × 5 ft black ball valve refrigerant hoses •Interchangeable hose color tags (red, yellow, blue) •Original Fieldpiece retail packaging Specifications Brand Fieldpiece Model HR3B Quantity 3 hoses Hose Length 5 ft (1.5 m) each Fitting Size 1/4 in × 1/4 in Valve Type Ball Valve Working Pressure 800 PSI Burst Pressure 4000 PSI Refrigerant Compatibility A2L and standard refrigerants Standards Permeation barrier meets SAE J2196 Construction Four-layer, full-ring triple crimp Applications Charging, recovery, evacuation Color Black, with red / yellow / blue ID tags Frequently Asked Questions Q: What does "A2L compatible" actually mean for me? A: A2L refrigerants like R-454B and R-32 are replacing R-410A across new equipment. They're mildly flammable and require hoses with a proper permeation barrier — otherwise refrigerant slowly migrates through the hose wall. These meet SAE J2196, so they're rated for both A2L and conventional refrigerants. Buy once, work on old and new systems. Q: Ball valve vs. low-loss valve — what's the difference? A: A ball valve gives you a positive quarter-turn shutoff you can see and feel — full flow open, fully closed shut. A low-loss valve is a depressor-style fitting that seals when disconnected. Ball valves offer better flow control during evacuation and a more definitive seal; that's why many techs prefer them for recovery work. Q: Will these fit my manifold? A: Yes, if it uses standard 1/4" flare connections — which nearly all HVAC manifolds do. Both ends are 1/4" × 1/4". If your gauge set uses 5/16" ports (some newer R-410A-specific manifolds), you'd need adapters or the HR3BM version instead. Q: Why 5 ft instead of 6 ft? A: Less hose to wrangle in tight mechanical rooms, attics, and rooftop units, and less internal volume to evacuate. If you routinely work at a distance from the unit, longer hoses may suit you better — but for most service calls 5 ft is the sweet spot. Q: The hoses are all black — how do I tell them apart? A: That's what the interchangeable color tags are for. Snap red on the high side, blue on the low side, yellow on the service line — or arrange them however your shop does it. Because they're removable, you can re-tag hoses as your setup changes. Q: What does "full-ring triple crimp" mean in practice? A: It's how the fitting is attached to the hose. Cheap hoses fail by pulling out or leaking at that junction under pressure. A full-ring triple crimp grips the hose around its entire circumference in three places — significantly more resistant to pull-out and the most common failure point on a charging hose. Q: Can I use these for automotive A/C? A: The fittings are standard 1/4" HVAC flare. Automotive systems use quick-couplers sized for R-134a or R-1234yf, so you'd need the appropriate coupler adapters. These are designed primarily for HVAC/R service work.
