Pack of 400 Foskan 1/2 in PEX Copper Crimp Rings - Durable Connections

Our review of the Pack of 400 Foskan 1/2 in PEX Copper Crimp Rings finds them best suited for plumbers and DIYers who need a reliable, high-volume supply of crimp rings for routine PEX installations and repairs. The single biggest reason to buy is consistency: these rings are made of high-strength copper with a black-oxidized finish that resists corrosion and helps create leak-proof joints when used with standard crimping tools. For anyone fitting multiple PEX runs or stocking a service van, the pack offers predictable performance and parts economy.

Key Features

• Premium Material: High-strength copper construction provides durable mechanical strength and resistance to corrosion for long-lasting PEX connections.
• Large Pack Quantity: A pack of 400 rings reduces trips to the supplier and keeps a steady supply on hand for multiple jobs or larger projects.
• Black-Oxidized Finish: Surface treatment improves corrosion resistance in humid or variable environments, helping maintain secure seals over time.
• Universal Compatibility: Designed to work with all common PEX tubing and crimp fittings, so you can use the same rings across different brands and systems.
• Efficient Crimping: Rings form reliable, quick connections when used with standard crimping tools, saving time on installs and repairs.

Who It's For

The pack is ideal for professional plumbers, HVAC technicians, and serious DIYers who perform frequent PEX installations or maintain rental properties and need a dependable bulk supply. It is particularly useful for service vans, job boxes, and projects that require many 1/2 in connections.

Those who only do occasional, single small repairs or who prefer alternative connection systems such as push-fit fittings might find a smaller pack or different system more economical; this product is optimized for volume and repeated use rather than one-off purchases.
