Brass Compression Double Ferrule Straight Connector — Reliable Leak-Free Joints for Copper Tube

When a leaking pipe joint costs you time, money, and a flooded cabinet, the fitting you choose matters. Whether you're a plumber running new copper lines or a DIYer tackling a bathroom renovation, these brass compression double ferrule straight connectors deliver a secure, tool-free seal that holds under pressure — no soldering required.

Each connector is machined from solid brass and uses a two-ferrule compression system (front ferrule + back ferrule) to grip the copper tube firmly on both ends. Available in equal-bore sizes from 15mm × 15mm (≈ 19/32" × 19/32") up to 42mm × 42mm (≈ 1-21/32" × 1-21/32"), plus a range of reducing sizes (20×15mm, 22×15mm, 22×16mm, 22×25mm, 22×28mm). Sold in 1, 3, 5, or 10-piece sets to match your project scale.

Ideal for residential water supply lines, radiant heating loops, and light commercial plumbing where a clean, reusable compression joint is preferred over soldered connections. The straight connector format suits inline tube-to-tube joins in tight spaces where a union fitting is needed quickly.

🔵 Compatibility: Designed for copper tube. Size refers to tube outer diameter (OD). Match fitting size to your tube OD — e.g., 22mm fitting for 22mm OD copper tube. Reducing sizes connect two different OD tubes inline.

✅ Key Features of These Brass Double Ferrule Compression Straight Connectors

  • 🔩Double Ferrule Grip — Two-ferrule design (front + back) creates a more vibration-resistant, leak-free seal compared to single ferrule compression fittings for copper tube.
  • 🟡Solid Brass Construction — Machined from brass for natural corrosion resistance, durability in damp environments, and long service life in plumbing and heating systems.
  • 📐Wide Size Range — Equal sizes from 15mm up to 42mm OD, plus five reducing configurations, covering the most common copper tube dimensions used in US and metric plumbing.
  • 🔧No Soldering Required — Wrench-only installation makes these straight connectors accessible for DIY plumbing repairs and professional retrofits without a torch or flux.
  • 📦Flexible Pack Sizes — Available in 1, 3, 5, or 10-piece sets so you can buy exactly what you need — whether it's a single repair or stocking up for a multi-fixture installation.
  • ♻️Reusable & Serviceable — Compression fittings can generally be disassembled and reassembled, making them a practical choice for installations that may need future access or adjustment.

❓ Frequently Asked Questions

How do I choose the right size compression fitting for my copper tube?

Match the fitting size to your tube's outer diameter (OD). For example, a 15mm × 15mm fitting is designed for 15mm OD copper tube. If you're working in inches, 15mm is approximately 19/32" and 22mm is approximately 7/8". Always measure the tube OD — not the inner diameter — before ordering.

What is a double ferrule compression fitting and how does it differ from a single ferrule?

A double ferrule fitting uses two ferrules (front and back) to grip the tube, which generally provides a more secure, vibration-resistant seal compared to single ferrule designs. This makes them well-suited for higher-pressure or more demanding plumbing applications.

Can these fittings be used outdoors or in humid environments?

Brass is naturally corrosion-resistant and typically performs well in damp or humid indoor environments. For direct outdoor exposure or aggressive environments, additional protection or a stainless steel alternative may be advisable. Contact us to confirm suitability for your specific application.

What thread standard do these compression fittings use?

These fittings generally use standard metric compression threads compatible with copper tube plumbing systems. Thread specifications vary by size — please contact us to confirm the exact thread standard for your chosen size before installation.

How much pressure can these fittings handle?

Brass double ferrule compression fittings are typically rated for working pressures suitable for residential and light commercial plumbing and gas applications. Exact pressure ratings depend on size and installation conditions. Contact us to confirm ratings for your specific use case.

Do I need any special tools to install these fittings?

In most cases, installation requires only standard wrenches — no soldering or special crimping tools needed. Hand-tighten the nut first, then use a wrench to tighten approximately 1–1.5 additional turns. Always follow local plumbing codes and manufacturer guidelines.

Are these fittings compatible with tubes other than copper?

These connectors are designed primarily for copper tube. They may also be compatible with certain brass or stainless steel tubing of the same outer diameter, but compatibility should be verified before use. Contact us if you need to use them with non-copper tubing.

Why should I buy multiple pieces at once?

Buying in 3, 5, or 10-piece sets reduces the per-unit cost and ensures you have spares on hand for future repairs or multi-point installations. This is especially useful for plumbers, contractors, and DIYers working on larger projects.
