Description
Product Overview
Patikil’s 4mm brass compression sleeves are engineered to meet the demanding standards of modern industrial and scientific installations. Crafted from high‑grade brass, each ferrule offers exceptional corrosion resistance, ensuring a long service life even in humid or chemically aggressive environments. The precision‑machined interior diameter of 4mm (0.16 inch) guarantees a snug fit for copper, brass, aluminum, or compatible plastic tubing, while the exterior brass finish provides a professional appearance and reliable mechanical strength. The set includes 25 individual ferrules, each weighing just 0.317 ounces, making them lightweight yet robust for repeated use.
These compression sleeves employ a standard NPT thread type, allowing seamless integration with existing pipe connectors and nuts. The design follows a proven compression principle: when the nut is tightened, the ferrule deforms slightly, creating a uniform seal that prevents leaks under pressure. This mechanism is ideal for both low‑pressure HVAC circuits and higher‑pressure hydraulic or pneumatic lines, delivering consistent performance across a wide range of applications.
Dimensions of each ferrule are compact—approximately 5.5 × 4.2 mm (D × H)—making them easy to handle and store. The packaging presents a clear 25‑piece count, simplifying inventory management for contractors, maintenance teams, and DIY enthusiasts alike. With a best‑seller rank of #61 in Compression Fitting Ferrules, these components have earned a reputation for reliability and ease of installation.
Usage
Patikil’s 4mm compression sleeves are versatile enough to serve in a variety of settings. In HVAC systems, they secure refrigerant lines and condensate drains, ensuring no moisture intrusion or refrigerant loss. For hydraulic applications, the ferrules provide a leak‑free connection between metal tubing and high‑pressure pumps, supporting fluid transfer in machinery, automotive lifts, and industrial presses. Pneumatic installations benefit from the same airtight seal, making these sleeves suitable for air compressors, control valves, and pneumatic actuators.
Beyond traditional industrial uses, the ferrules are also valuable in residential and commercial plumbing projects. They can be employed to join copper water lines, connect humidifier supply tubes, or secure decorative lighting fixtures that rely on metal conduit. The reusable nature of the brass ferrules means that technicians can disassemble and re‑assemble connections without compromising seal integrity, reducing waste and lowering long‑term costs.
Installation is straightforward: insert the appropriately sized copper or compatible pipe into the sleeve, position the ferrule over the pipe end, and tighten the accompanying nut until the ferrule compresses evenly. This simple process requires only basic hand tools, making it accessible to both seasoned professionals and hobbyists. The result is a durable, leak‑free joint that can withstand temperature fluctuations and vibration.

FAQ
What pipe sizes are compatible with the 4mm ferrules?
The 4mm (0.16 inch) ferrules are designed for tubing with an outer diameter of 4mm. They work well with copper, brass, aluminum, and compatible plastic pipes that match this specification.
Can these ferrules be used in high‑pressure hydraulic systems?
Yes. The brass material and compression design allow the ferrules to maintain a leak‑free seal under typical hydraulic pressures. For extremely high‑pressure applications, verify the system’s pressure rating against the ferrule’s specifications.
How do I install the compression sleeves correctly?
Insert the pipe end into the sleeve, place the ferrule over the pipe, then tighten the nut until the ferrule compresses evenly. Ensure the pipe is fully seated before final tightening to achieve a proper seal.
Are the ferrules reusable after removal?
Absolutely. Brass ferrules can be removed and reinstalled multiple times without losing their sealing capability, making them a cost‑effective choice for projects that require frequent maintenance.
What warranty does Patikil provide for these fittings?
Patikil offers a standard one‑year warranty covering manufacturing defects. If you encounter any issues, contact our support team for assistance and replacement options.
