Brass Male Compression Fittings — Reliable BSP Hydraulic Adaptors for Tubing Connections

Leaking fittings and mismatched thread standards are among the most frustrating problems for anyone building or maintaining pneumatic, hydraulic, or plumbing lines. Whether you're a workshop technician, a DIY plumber, or a small-scale machine builder, finding brass male compression fittings that actually seal cleanly and thread in without cross-threading can feel like a chore. These BSP hydraulic adaptor fittings are designed to take that frustration off the table.

Each fitting is machined from solid brass and features a male BSP (British Standard Pipe) thread on one end and a compression-style tube connection on the other. Available in PC4 through PC16 sizes — accepting tube outer diameters from 4mm (≈5/32") up to 16mm (≈5/8") — with BSP thread sizes ranging from 1/8" to 1/2" bore depending on the variant. Sold in convenient multi-packs of 2, 5, 10, or 20 pieces so you can stock the right quantity for your project or maintenance kit.

These fittings are well suited for compressed air distribution lines in workshops, water supply connections in residential plumbing, and light hydraulic oil circuits in industrial or agricultural equipment. The BSP thread standard makes them a natural fit for European and Asian-spec machinery, pneumatic cylinders, and hydraulic manifolds where NPT threads are not used.

🔵 Compatibility Note: These fittings use BSP (British Standard Pipe) threads — BSPP or BSPT depending on variant. They are not directly interchangeable with NPT (National Pipe Thread) fittings. Please verify your port thread standard before ordering. Tube OD must match the PC size selected (e.g., PC6 = 6mm OD tube).

⚠️ Spec Confirmation: Exact thread pitch, wall thickness, and pressure rating vary by size. If your application has specific pressure or media requirements, please contact us to confirm before purchasing.

✅ Key Features of These Brass Male Compression Fittings

🔩BSP Male Thread — Male BSP (British Standard Pipe) thread provides a secure, standardized connection to hydraulic ports, manifolds, and pneumatic cylinders commonly found in European and Asian equipment.
🪛Compression-Style Tube Grip — The compression fitting design grips the tube OD firmly without requiring soldering or flaring, making installation straightforward for both workshop and field use.
🟡Solid Brass Construction — Machined from brass for good corrosion resistance, machinability, and compatibility with air, water, and light oil media — a reliable choice for brass compression fitting applications.
📐Wide Size Range (PC4–PC16) — Covers tube ODs from 4mm to 16mm (≈5/32" to 5/8"), with BSP bore sizes from 1/8" to 1/2", giving you flexibility across multiple line sizes in a single product family.
📦Multi-Pack Quantities — Available in 2, 5, 10, or 20-piece packs so you can order exactly what you need — whether it's a single repair or stocking a maintenance inventory of hydraulic adaptor fittings.
⚙️Versatile Application Fit — Suitable for compressed air lines, water supply connections, and light hydraulic circuits — a practical BSP to tube adaptor for workshops, plumbing, and light industrial use.

❓ Frequently Asked Questions

How do I choose the right compression fitting size?

Match the PC size to your tubing outer diameter — for example, PC6 fits 6mm (≈1/4" OD) tubing. For the BSP thread end, measure the male thread diameter on your port and match it to the fitting's thread designation (e.g., 1/8" BSP, 1/4" BSP). When in doubt, measure both the tube OD and the port thread before ordering. A thread gauge or caliper is the most reliable way to confirm sizing.

What tube sizes do these fittings accept?

These fittings cover PC4 (4mm OD), PC6 (6mm OD), PC8 (8mm OD), PC10 (10mm OD), PC12 (12mm OD), PC14 (14mm OD), and PC16 (16mm OD) tube outer diameters. The bore range corresponds to approximately 1/8" to 1/2" BSP depending on the variant selected. See the size chart above for the full breakdown.

What pressure rating do these brass compression fittings typically handle?

Brass compression fittings of this type generally handle working pressures up to 150–300 PSI depending on tube size and wall thickness. For hydraulic applications above these ranges, please contact us to confirm suitability for your specific system before ordering.

Can these fittings be used outdoors or in wet environments?

Brass offers good corrosion resistance for most indoor and mildly humid outdoor environments and is generally suitable for water, air, and light oil lines. For highly corrosive environments or saltwater exposure, stainless steel fittings are typically recommended instead. If you're unsure, contact us with your application details.

Are these fittings compatible with BSP (British Standard Pipe) threads?

Yes — these are male BSP hydraulic adaptors. BSP threads are widely used in European and Asian hydraulic and pneumatic systems. They are not directly interchangeable with NPT (National Pipe Thread) fittings used in North American plumbing. Please verify your port thread standard before ordering to avoid compatibility issues.

What media are these fittings suitable for?

These brass compression fittings are generally suitable for compressed air, water, and light hydraulic oil lines. They are not recommended for strong acids, ammonia-based fluids, or high-pressure steam without further confirmation. If your application involves aggressive media, contact us before purchasing.

Do I need thread sealant with these fittings?

For BSPP (parallel) threads, a thread sealant such as PTFE tape or thread compound is typically recommended to ensure a leak-free seal. BSPT (tapered) threads may seal on the taper alone, but sealant is still advisable for pressurized systems. Always follow the torque and sealant recommendations for your specific application.
