Brass Pipe Bushing Sleeve — Precision-Machined Cylindrical Spacer for Shafts, Bearings & Fittings

When a loose shaft rattles in its housing or a plumbing reducer doesn't quite bridge the gap, the right brass pipe bushing sleeve makes the difference between a solid repair and a recurring headache. Machinists, plumbers, maintenance technicians, and serious DIYers rely on these cylindrical brass sleeves to fill bore gaps, reduce shaft diameters, act as bearing liners, and serve as structural spacers in both indoor and outdoor assemblies.

Each piece is a solid-wall cylindrical brass sleeve, sold individually (1 PCS per order). Outer diameters range from 25mm (≈1.0") to 100mm (≈3.94"), inner diameters from 15mm (≈0.59") to 70mm (≈2.76"), with a fixed length of 100mm (≈3.94"). Wall thickness varies by size combination — for example, the 25mm OD × 15mm ID variant has a 5mm (≈0.20") wall, while the 100mm OD × 50mm ID variant has a 25mm (≈0.98") wall. All sizes are available as individual pieces so you can order exactly what your project requires.

Typical use cases include shaft-to-housing adapters in light machinery, pipe reducer sleeves in plumbing and HVAC systems, bearing liner replacements in agricultural equipment, and precision spacers in custom fabrication and woodworking jigs. The machinability of brass also makes these sleeves a go-to choice for prototype builds and one-off repair jobs where a custom-length bushing is needed.

ℹ️ Compatibility Note: These are plain, unthreaded cylindrical sleeves. OD fits into the housing bore; ID fits over the shaft. Verify both dimensions against your application before ordering. All sizes listed are nominal metric measurements.

✅ Key Features of These Brass Pipe Bushing Sleeves

  • 🔩Wide Size Range — OD 25–100mm and ID 15–70mm in a single product line, covering the most common shaft-to-housing bushing sizes for light machinery and plumbing applications.
  • 🛡️Corrosion-Resistant Brass Construction — Copper-zinc alloy resists rust, oxidation, and moisture, making these sleeves reliable in wet, humid, and outdoor environments without surface treatment.
  • ⚙️Easy to Machine & Cut — Brass cuts cleanly with standard metalworking tools, so you can trim to a custom length, bore to a tighter ID, or turn the OD down to fit non-standard housings.
  • 📐Consistent 100mm Length — A standardized 100mm (≈3.94") length gives you a reliable starting point for spacer and bushing applications, with enough material to cut down if a shorter sleeve is needed.
  • 🔄Versatile Cross-Application Use — Suitable as bearing liner sleeves, pipe reducer adapters, shaft spacers, and structural inserts across plumbing, HVAC, woodworking, and light industrial fabrication.
  • 📦Single-Piece Ordering — Buy exactly the quantity you need — no forced multi-packs. Each variant ships as 1 PCS, ideal for repair jobs, prototypes, and low-volume custom builds.

❓ Frequently Asked Questions

How do I choose the right OD and ID for my application?

Measure the shaft or bore you need to fit. The Inner Diameter (ID) should match the shaft OD with your desired clearance, and the Outer Diameter (OD) should fit snugly into the housing bore. For example, a 25mm OD × 15mm ID sleeve fits a 15mm shaft inside a 25mm housing bore. When in doubt, allow 0.01–0.05mm clearance for a sliding fit.

What load or pressure can these brass sleeves handle?

Brass pipe bushings generally handle moderate radial loads in low-to-medium speed applications. Brass typically has a compressive strength of around 60,000–80,000 psi, making it suitable for light machinery, plumbing fittings, and structural spacers. For heavy dynamic loads, consult an engineer to confirm suitability.

Are these brass sleeves suitable for outdoor or wet environments?

Yes. Brass is naturally corrosion-resistant and performs well in humid, wet, and mildly corrosive environments. It is generally suitable for outdoor plumbing, marine fittings, and garden irrigation systems. For highly saline or chemical-exposure environments, verify compatibility with your specific conditions before installation.

Do these sleeves have pipe threads or any connection standard?

No. These are plain (unthreaded) cylindrical sleeves — they do not have NPT, BSP, or any other pipe thread. They are designed as spacers, bushings, or structural inserts that press or slide into a housing bore. If you need threaded brass fittings, please contact us to confirm compatibility.

Can I cut or machine these brass sleeves to a shorter length?

Yes. Brass machines easily with standard metalworking tools — a hacksaw, lathe, or pipe cutter will all work cleanly. Always deburr cut edges before installation to avoid damage to mating shafts or seals. The 100mm starting length gives you enough material for most custom-length bushing applications.

How do I decide between a thin-wall and thick-wall sleeve?

Wall thickness equals (OD − ID) ÷ 2. Thinner walls (e.g., 5mm wall on a 25mm OD × 15mm ID) are lighter and suit tight-clearance housings. Thicker walls (e.g., 25mm wall on a 100mm OD × 50mm ID) provide more structural rigidity and load-bearing capacity. Choose based on your housing bore size and the strength required for your application.

What is the difference between a brass pipe bushing and a bronze bushing?

Brass is a copper-zinc alloy, while bronze is a copper-tin alloy. Both are corrosion-resistant, but bronze generally offers slightly better wear resistance for bearing applications. These sleeves are made from brass, making them well-suited for structural, plumbing, and general-purpose spacer uses where machinability and corrosion resistance are the primary requirements.
