SKU CH-Q33M-25RY9

Straight copper tubing, Type K, 1/4 in outside diameter and 3 ft long, supplied in a pack of five

  • Type K copper meets ASTM B251 standard
  • Hard temper provides rigid, straight 3 ft runs
  • 222 in inside diameter for precise flow control
  • 014 in wall thickness balances strength and weight
  • Supplied in 5-piece packs for multiple installations

Copper Type K Tubing for General Use

This straight copper tube meets ASTM B251 specifications and ships in a five-piece package. Each length measures three feet with a quarter-inch outside diameter. The hard temper and point-zero-one-four-inch wall thickness suit general-purpose plumbing and refrigerant lines.

Fits Quarter-Inch Flare or Compression Fittings

The point-two-two-two-inch inside diameter accepts standard quarter-inch connectors without adapters. Rigid hard temper holds shape during bending so fewer supports are needed. Copper construction allows sweat soldering or press-connect methods depending on installer preference.

Withstands Pressure Over Long Runs

Thick Type K walls resist work-hardening and vibration fatigue better than thinner-wall alternatives. Hard temper maintains dimensional stability under sustained system pressure. Copper's natural corrosion resistance protects the line set through seasonal temperature cycles.
