10mm High Pressure Compression Union

Tackle metric fuel, brake, and hydraulic lines with confidence using our 10 mm high-pressure compression union. Machined from nickel-plated brass and lab-tested beyond 3,000 psi (207 bar), this three-piece fitting delivers leak-proof performance—no flaring or soldering required. Join two 10 mm hard lines in minutes and get back on the road or jobsite.

Built for serious pressure

Cold-forming ferrule design: Bites into steel, copper-nickel, or stainless tubing for a permanent gas-tight seal.

Black Oxide-plated body: Combats road salt, ethanol, diesel, and hydraulic fluid corrosion.

True high-pressure rating: Exceeds FMVSS 106 brake-impulse standards and handles power-steering or hydro-boost pressures.

Quick install: Square-cut, deburr, slide nut + ferrule, tighten to spec—done.

Metric accuracy: Threads and bore precisely matched for 10 mm OD tubing.

Ideal applications

Metric brake hard lines • Diesel feed & return • Hydro-boost conversions • Power-steering pressure runs • Off-road air-locker plumbing • Industrial hydraulics up to 3 kpsi

Two-minute install

  1. Cut both tube ends square; deburr inside and out.

  2. Slide compression nut and ferrule onto each tube.

  3. Insert tube fully into union body; finger-tighten nuts.

  4. Wrench an additional 1¼ turns (see torque chart on the bag).

  5. Pressure-test—no bubbles, no drips, ready to roll.

Shop tip: A dab of light oil on the nut threads helps hit full clamp load smoothly.
