BSPT Compression Fitting 90° Elbow Male Connector — Leak-Free Stainless Steel for Fluid & Pneumatic Lines

When a straight run isn't an option and a leaking joint isn't acceptable, plumbers, HVAC technicians, and DIY builders need a fitting that changes direction without compromising the line. Whether you're routing a coolant line around a bracket, connecting a pneumatic tube to a valve block, or plumbing a water system in a tight cabinet, a loose or corroded fitting can mean hours of rework. This 90° elbow male coupling connector is built for those situations where reliability and a clean 90-degree turn matter.

Each fitting is machined from 304 stainless steel and combines a male BSPT tapered thread on one end with a compression sleeve connection on the other. Available in BSPT thread sizes from 1/8" to 1/2" and tube outer diameters from 6mm (≈1/4") to 20mm (≈3/4"), these fittings cover the most common metric tube sizes used in fluid and pneumatic systems. Sold individually or in value packs of 3, 5, or 10 pieces.

Typical use cases include connecting stainless steel or copper tubing to BSPT-threaded valve ports in water treatment systems, routing pneumatic lines in compressed air assemblies, and plumbing coolant or hydraulic lines in industrial equipment where a 90-degree direction change is required. The compression design eliminates the need for soldering or flaring, making it a practical choice for field repairs and new installations alike.

🔗 Thread Compatibility: These fittings use BSPT (British Standard Pipe Taper) threads — not NPT. BSPT and NPT are not interchangeable. Confirm your port thread standard before ordering. Tube OD sizes are metric (6–20mm); measure your tube's outer diameter to select the correct variant.

✅ Key Features of These BSPT Stainless Steel Compression Elbow Fittings

  • 🔩90° Elbow Design — Routes tubing around obstacles and through tight spaces without bending or kinking the tube, maintaining full flow capacity through the turn.
  • 🛡️304 Stainless Steel Construction — Resists rust, oxidation, and general corrosion in water, air, and mild chemical environments, making it suitable for both indoor and outdoor installations.
  • 🔧No-Solder Compression Connection — The compression sleeve creates a mechanical seal directly on the tube OD — no torch, no flaring tool, no special skills required for a secure BSPT compression fitting installation.
  • 📐Wide Size Range — BSPT thread sizes from 1/8" to 1/2" paired with tube ODs from 6mm to 20mm cover the most common metric tube sizes used in pneumatic and fluid systems.
  • 💧Leak-Resistant Tapered Thread — The BSPT male taper thread self-seals as it's tightened into the port; combined with PTFE tape, it provides a reliable seal in pressurized water and air lines.
  • 📦Flexible Pack Quantities — Available in 1, 3, 5, or 10-piece packs so you can order exactly what you need for a single repair or stock up for ongoing maintenance and installation work.

⚠️ Sizing Note: The tube OD dimension refers to the outside diameter of your tubing — not the inside. Using the wrong OD size will result in a loose or leaking compression joint. If you are unsure, measure your tube with calipers before selecting a variant.

❓ Frequently Asked Questions

How do I choose the right size for this compression fitting?

You need two measurements: the BSPT thread size (the male threaded end that screws into your port — typically 1/8" to 1/2") and the tube outer diameter (OD) for the compression sleeve end (6mm to 20mm). For example, BSPT 1/4" x 8mm means a 1/4" male thread with an 8mm (≈5/16") tube OD. Always measure your existing port thread and tube OD before ordering.

What tube OD sizes are available, and what are the inch equivalents?

Available tube ODs and approximate inch equivalents:

  • 6mm ≈ 1/4"
  • 8mm ≈ 5/16"
  • 10mm ≈ 3/8"
  • 12mm ≈ 1/2"
  • 14mm ≈ 9/16"
  • 16mm ≈ 5/8"
  • 18mm ≈ 11/16"
  • 20mm ≈ 3/4"

Select the size that matches your tube's outer diameter — not the inner diameter.

How strong is this fitting — what pressure can it handle?

304 stainless steel compression fittings are generally rated for working pressures up to approximately 150–300 PSI depending on tube size and wall thickness. Always verify the pressure rating against your specific system requirements and consult your system's documentation before installation in high-pressure applications.

Can this fitting be used outdoors or in corrosive environments?

Yes. 304 stainless steel offers good corrosion resistance for most outdoor, humid, and mildly corrosive environments. It is not recommended for prolonged exposure to chloride-rich environments (e.g., saltwater or marine applications) — for those, 316 stainless steel is typically preferred.

Is BSPT the same as NPT? Will this fit my American pipe fittings?

No — BSPT (British Standard Pipe Taper) and NPT (National Pipe Taper) are not interchangeable. Both are tapered threads but have different thread angles (55° for BSPT vs. 60° for NPT) and pitch. Forcing them together can cause leaks or thread damage. Confirm your port uses BSPT threads before ordering. If your system uses NPT ports, you will need an NPT-compatible fitting.

Do I need thread sealant (PTFE tape) with this fitting?

For the male BSPT threaded end, applying PTFE tape or thread sealant is generally recommended to ensure a leak-free seal, especially in pressurized fluid or gas systems. The compression sleeve end creates its own mechanical seal on the tube and typically does not require additional sealant.

What types of tubing work with compression fittings?

Compression fittings are generally compatible with copper, brass, aluminum, and certain rigid plastic tubing (such as nylon or polyethylene) that matches the specified outer diameter. Soft or corrugated tubing is not recommended as it may not form a reliable seal under the compression ferrule.

Can I reuse this compression fitting after disassembly?

Compression fittings can generally be disassembled, but reuse is not always recommended in critical pressure applications. The ferrule (compression ring) deforms slightly when first tightened to create the seal. If reusing, inspect the ferrule carefully for deformation or damage and replace if necessary.
