Those fittings are called Qest and can be purchased here: https://www.plumbingsupply.com/polyb.html
You can get barbed adapters at Lowes and HD for Qest to Pex pipe. IIRC they are labels PB to Pex. The pipe is called polybutylene. They entire product line was part of a class action lawsuit which the company (Zurn) lost. The material is particularly prone to clorine embrittelment.
