The ANDERSON METALS CORP 710081-06 is a 3/8-inch compression cap designed to terminate or seal off a compression-type water supply line. This fitting installs onto a standard 3/8-inch compression tube end, creating a secure, leak-resistant closure without soldering or threading. It meets lead-free compliance requirements under Public Law 111-380, making it suitable for potable water applications where low-lead content is mandated. Plumbers and pipefitters install this fitting during service, renovation, or system modifications when a supply line must be capped and sealed. The carded packaging and 10-unit pack quantity make it a practical stocking item for service vehicles and supply rooms.
This compression cap is suited for residential and light commercial plumbing applications. Typical install scenarios include capping off unused supply stubs, sealing lines during phased construction, or isolating a section of tubing during repair work. The 3/8-inch compression connection is a standard size commonly found on water supply lines serving fixtures such as faucets, toilets, and ice makers. The lead-free construction satisfies requirements for potable water contact in states and jurisdictions enforcing low-lead plumbing standards.
Designed as an OEM-style replacement and standard-use compression cap compatible with 3/8-inch OD compression tubing in residential and light commercial potable water systems.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Always shut off the water supply and relieve line pressure before installing or removing any compression fitting. Hand-tighten the compression nut first, then use an appropriately sized wrench to snug the connection — avoid over-tightening, which can crack the ferrule or fitting body. Inspect for leaks after restoring pressure.
