FAQ (Frequently Asked Questions)

What is the difference between Schedule M and L copper pipes ?

The main difference between Schedule M and Schedule L copper pipes is their wall thickness. Schedule L copper pipes have thicker walls, making them more durable and better suited for higher-pressure applications, while Schedule M copper pipes have thinner walls, making them lighter, more economical, and suitable for low- to medium-pressure plumbing systems.

Is ASTM B88 Type K or Type L ?

ASTM B88 is a standard that covers Types K, L, and M copper water tubes. Type K has the thickest wall for high-pressure and underground applications, while Type L has a medium wall thickness and is widely used for plumbing, HVAC, and medical gas systems.
