When you're servicing or installing refrigeration lines, the component you need depends on the job: adding a service port, isolating a section for repair, connecting a manifold for charging, or quickly coupling a line. The four parts here cover those different needs, with listed prices from $12.99 to $69.99. Here's how to match each one to the work you're doing.
Quick take
The RectorSeal PRO-Fit union gives you a quick-connect way to join a 1/4" refrigerant line at the lowest listed price. The SUPCO BPV31 is a piercing valve that fits 1/4", 5/16", and 3/8" tubing and is rated for 500 PSI. The 1/2" ODF ball valve is a brass shut-off valve with an access port for sweat/solder installations. And the Fieldpiece HR3B is a three-hose set with ball valves and 1/4" x 1/4" connections for leak testing and vacuuming tasks.

Product notes
Fieldpiece HR3B Ball Valve Refrigerant Hose Set
At $69.99, this is the highest-priced item in the group and the only complete hose set here. It includes three 1/4" x 1/4" ball valve hoses with color tags, so you can keep suction, discharge, and liquid lines separate during recovery or vacuuming. The set is built for leak testing and vacuuming on a central air conditioner, and it has heavy-duty construction. One limitation: at 14 inches in diameter, it's a bulkier kit than a single valve or union. If you only need a tap or a shut-off, this set gives you more than the job requires. Choose it when you want a ready-to-go hose set with color-coded lines.
1/2" ODF Refrigeration Ball Valve with Access Port
Listed at $29.99, this brass ball valve is a manual shut-off for isolating a section of the system. It has a forged brass body, copper connection tubes, and an integrated access port, making it suitable for pressure monitoring, charging, or recovery once installed. The 1/2" ODF design uses sweat/solder connections for installation into copper line. One limitation: it's a single valve, so it doesn't include hoses or extra fittings. Choose it when you need a discrete shut-off valve with an access port for central air conditioning service.
SUPCO BPV31 Bullet Piercing Valve
At $15.99, the SUPCO BPV31 is a 3-in-1 piercing valve that fits 1/4", 5/16", and 3/8" copper tubing. It's rated for 500 PSI and can be used on refrigerants such as R12, R22, R410A, R134a, R404A, and R407C. The brass body is corrosion-resistant, and the patented gasket is designed to give a leak-free seal when you tap a sealed line. The biggest limitation is that this is a service tap for diagnostics or recharging, not a shut-off valve or a full hose set. It's intended for central air conditioners, which fits the task of adding a service port to an existing line.
RectorSeal 87018 PRO-Fit 1/4" Quick Connect Union
The RectorSeal 87018 is the least expensive option here at $12.99. It's a 1/4" quick-connect union for refrigerant lines, designed so you can connect and disconnect without cutting the line. The PRO-Fit design offers a strong, durable construction for HVAC and refrigeration use, and it's made in the United States. The limitation is that this is a straight union: it doesn't provide a shut-off function, a piercing tap, or a hose set. If your job is simply coupling two refrigerant lines or making a clean break for service, this low-priced union gives you that specific function at the lowest listed price.
Final recommendation by use case
Pick the Fieldpiece HR3B if you need a complete three-hose set with ball valves for leak testing and vacuuming. Choose the 1/2" ODF ball valve if you need a brass shut-off valve with an access port for a sweat/solder line. Grab the SUPCO BPV31 if you need a piercing valve to tap an existing line for service. Opt for the RectorSeal 87018 if you need a straightforward 1/4" quick-connect union at the lowest listed price.
