Question 98Refrigeration & AC - 1st Asst/Chief

The correct answer is A) Hard drawn copper tubing is not easily flared, bent, or swaged, so brazed fittings are commonly used. Hard drawn copper tubing is a stiffer and less malleable form of copper tubing, making it more difficult to flare, bend, or swage compared to soft annealed copper tubing. Due to this, brazed fittings are commonly used with hard drawn copper tubing to create secure, leak-proof connections, as flare or compression fittings may not be as effective. The other answer choices are incorrect because: B) hard drawn copper is not easily swaged, C) it is not easily bent, and D) it is not easily flared, so flare fittings are not commonly used.
