Metal Air Line Fittings Straight Connectors 🔧

A set of metal straight pneumatic fittings for compressed-air circuits — joining air tubing to threaded ports in a simple in-line layout. Built as practical hardware for air tools, compressors, pneumatic cylinders, valves and workshop automation setups.

⚙️ Metal Fitting Body 📏 Straight In-Line Connector 🧰 Air Tools & Compressors 🔩 Quick Tube Connection
01 Straight Pneumatic Layout In-line male connector joins air tubing straight into a threaded port without elbows, branches or direction changes.
02 Metal Body Construction Metal housing intended for repeated connection cycles in workshop use; confirm exact alloy, plating and internal seal materials on the spec sheet.
03 Compressed Air Applications Suits standard PU and nylon/PA air tubing in pneumatic tools, cylinders, valves, filter regulators, compressors and bench rigs.
04 Ready Spare Fitting Set Supplied as a multi-piece set for repairs, line extensions, new builds and keeping spare connectors in your pneumatic parts kit.
Pneumatic Performance

Secure Connections On The Air Line

A straight fitting keeps the air path short and direct: the tube end locks into the connector, while the threaded port mounts into a tool, valve, cylinder or manifold. Confirm both your tube OD and thread standard before selecting the fitting size.

  • Push-In Tube Lock: On push-to-connect variants, square-cut the air tube, insert firmly until seated, and verify the grip; press the release collar to remove the tube when servicing.
  • Threaded Straight Port: Male thread screws into the mating pneumatic component; match NPT, BSP/BSPT or metric standards — these threads are not interchangeable.
  • Internal Seal Assembly: Sealing ring and locking claw retain the tube and seal the air path; material and design vary by supplier model.
  • Reusable Shop Hardware: Fittings can be released, reused and rearranged during line changes rather than replacing an entire air assembly.
Workshop Ready

For Tools, Cylinders & Air Systems

Keep a matched set on hand wherever compressed air lines are assembled, repaired or extended. Straight connectors are the everyday building block between flexible air hose and fixed threaded ports.

🧰 Wide Pneumatic Uses Air tools, spray guns, nail guns, cylinders, solenoid valves, filter-regulator units, compressors, robotics and DIY bench setups.
🛠️ Maintenance Spares Use for leaking-line replacements, custom air extensions, troubleshooting and keeping a spare assortment in your tool chest.
📏 Match Before You Buy Measure your existing tube outside diameter and thread size; mismatched NPT/BSP/metric threads will not seal or fit properly.

Specifications & Details

Product Specifications

Overview for the Metal Air Line Fittings Set. Values below marked for confirmation must be filled from the supplier spec sheet, model label or product listing before publishing.

Product Name 🔧 Metal Air Line Fittings Set – Straight Pneumatic Connectors
Fitting Type Straight in-line pneumatic male connector (tube-to-thread); confirm whether push-to-connect, barbed or quick-coupler design on this variant
Body Material Confirm material: solid brass, nickel-plated brass, zinc alloy or plated steel; confirm lock claw and O-ring/seal materials
Air Tube Connection Confirm compatible tube outside diameter (metric 4 / 6 / 8 / 10 / 12 mm or inch sizes) and approved tubing type such as PU, nylon or PA
Thread Standard Confirm NPT, BSP, BSPT, G or metric M thread size, male/female orientation, and whether a hex or installation flat is provided
Medium Compressed air per default; other fluids, water or gas require explicit supplier rating and must not be assumed
Working Pressure Confirm maximum working pressure, proof pressure and vacuum rating from the supplier sheet; system pressure is also limited by the connected tubing and hose
Working Temperature Confirm approved temperature range for the fitting, seals and matched tubing before installation in heated or cold environments
Set Quantity Confirm piece count, whether all fittings share one size or include mixed sizes, and any color-coded sleeve included in the package
Package Includes Fittings set as supplied; thread sealant, PTFE tape and tools are generally not included unless explicitly listed
⚠️ Thread sizes, tube OD, pressure rating, temperature range, alloy/plating, piece count and certifications are not stated in the source title — verify every value with the supplier before listing. NPT and BSP threads are not interchangeable. Shut off and depressurize the air system before installation or service; use the correct thread sealant or tape for tapered threads, do not over-tighten metal threads into plastic ports, and pressure-test the line before normal operation. These fittings are rated for compressed air applications only unless the supplier states otherwise.
Customer Reviews

Trusted By Workshop Builders

★★★★★ "Clean in-line air connections" “Matched these to my existing PU tubing after measuring the OD and thread. The straight layout keeps my bench air line neat and easy to route.” — Sample review: replace with real buyer feedback
★★★★★ "Solid metal finish" “Body feels solid compared with plastic fittings I have used before. Reused on a couple of line changes without stripping the thread.” — Sample review: replace with real buyer feedback
★★★★★ "Good spare set for the tool chest" “Kept as spares for air tool repairs. Make sure to confirm thread and tube size before ordering — matching the specs worked out well.” — Sample review: replace with real buyer feedback
Frequently Asked Questions

Product FAQ

Common questions about connection style, sizing, thread compatibility, sealing and working pressure.

Are these push-to-connect or barbed fittings?
Confirm the connection style on your purchased variant. For push-to-connect fittings, cut the tube square, remove burrs, insert it firmly until the locking collar seats, and give the tube a gentle pull to verify grip. Press the release collar evenly to disconnect. Barbed or quick-coupler models follow a different installation method shown in the supplier manual.
How do I choose the right size?
Two measurements must match: the air tube outside diameter (metric or inch) and the port thread size on your tool, valve or cylinder. Read the existing fitting markings, measure with calipers, and confirm whether the thread is NPT, BSP/BSPT or metric. When uncertain, send the supplier photos and dimensions before purchase; an incorrect size will not seal or may cross-thread.
What can these fittings be used for?
They connect compressed-air circuits: air compressors, air tools, spray guns, nail guns, pneumatic cylinders, solenoid valves, filter-regulator-lubricator units, automation rigs and workshop bench lines. Confirm the medium rating before any water, oil, fuel or gas application.
Do I need thread sealant or PTFE tape?
Tapered threads such as NPT and BSPT typically require PTFE tape or approved thread sealant; straight O-ring sealed threads rely on the internal seal and should not be wrapped. Follow the supplier installation guide, apply sealant only where required, and avoid over-tightening, especially when threading into aluminum or plastic ports.
What pressure can the fittings handle?
The working pressure range is stated on the supplier spec sheet and must be matched to your system. The maximum safe pressure of an assembled air line is also limited by the tubing, hose, couplings and connected components, not the fitting alone. Depressurize the system before installation and test the joint before resuming operation.
What material are the fittings made from?
Confirm the exact body alloy and surface finish for your variant, commonly brass or nickel-plated brass with a stainless steel locking claw and rubber O-ring on push-in models. Brass offers typical air-line corrosion resistance; plating mainly changes surface appearance and scratch protection. Verify the listing or supplier label before purchase.
How many fittings are in the set?
Set quantity and size mix are listed in the product variant details — confirm the piece count and whether the set is a single size or assorted before checkout. Sealant, tape, wrenches and spare O-rings are not included unless the package list explicitly states them.
