100-PCs HeSun Expansion Pex Angle Stop Valve - Pack for Plumbers

In this review the focus is on the 100-PCs HeSun Expansion Pex Angle Stop Valve pack and why it suits installers who need a reliable bulk supply. The bottom line: this 100-pack is intended for plumbers, contractors, and serious DIYers who work with PEX-A systems and need a consistent, lead-free angle stop that connects 1/2' PEX-A via expansion and delivers a 3/8' OD compression outlet. The biggest reason to buy is simple: it pairs ASTM F1960 expansion compatibility with a compression outlet in a large, value-conscious quantity, so it removes guesswork on fittings and reduces repeat ordering.

Key Features

• Connection type: Designed with a 1/2' PEX-A expansion inlet, it fits PEX-A pipes using expansion rings for a secure, code-friendly joint.
• Compression outlet: The 3/8' OD compression outlet accepts stainless steel bellows and supply lines for a common fixture connection without adapters.
• Safety assured: Constructed from lead-free brass with a chrome-plated finish and UPC certification to ensure potable water compatibility.
• Versatile control: The 1/4 turn shut off lets you isolate individual fixtures during repairs without shutting down the whole water supply.
• Durability: Brass construction resists corrosion and rust and is rated for use at temperatures up to 200F, supporting long-term, leak-free service.
• Bulk package: Supplied as a 100-pack so contractors can stock up and complete multiple installs without frequent reordering.

Who It's For

This 100-pack is aimed at professional plumbers, remodel contractors, and high-volume DIYers who regularly install PEX-A systems and need a dependable angle stop on every job. The pack size and ASTM F1960 expansion inlet make it especially useful for new construction and bathroom or sink rough-ins where many identical valves are required.

Those who should look elsewhere include homeowners who only need one or two valves for a single repair and prefer retail-size packaging, and projects that use PEX variants other than PEX-A without compatible expansion tooling, since the fitting is intended for expansion-style connections.
