Good quality.

For PEX A
These PEX A fittings meet all PEX A standards for use with any brand PEX A tubing. Not much more to say. PEX A is an expansion type PEX. This fitting will not work with crimp systems, that would be PEX B.

Defiantly Shark bite product
Defiantly Shark bite product got the Type A needed the Type B. Not going to return, don't want to deal with the hassle. Going to try to heat the pipe then shove it on. We will see if this works?

The adapter was an excellent choice for my plumbing project. It appears to be made from durable brass. Its compatibility with PEX-A tubing and ease of installation make it a top pick for the project. The adapter's versatility and reliable performance justify its cost, ensuring a secure, leak-free connection. Highly recommended for quality and ease of use.
