Legend Valve LEGE-450-991P Epdm O-ring 1/2 Inch Press Fitting

Product Description

The LEGEND VALVE LEGE-450-991P is a 1/2 inch EPDM replacement O-ring designed for use with press fittings in plumbing and piping systems. EPDM (ethylene propylene diene monomer) rubber provides reliable sealing performance and resistance to water, heat, and common chemicals encountered in potable water and hydronic applications. This O-ring meets NSF/ANSI 61 standards, making it suitable for systems carrying drinking water. Licensed plumbers and pipefitters install this component when servicing or assembling press-fit connections on copper, stainless, or carbon steel pipe systems.

This O-ring is used in residential and light commercial plumbing installations wherever press fittings are employed. It serves as a direct replacement when an existing O-ring is damaged, missing, or degraded during a repair or system expansion. Press fitting systems are commonly used in tight spaces or retrofit applications where open flame soldering is not practical or permitted. The LEGE-450-991P fits 1/2 inch press fitting connections and is appropriate for potable water distribution and heating and cooling piping circuits.

Key Features

• EPDM construction provides strong resistance to water, heat, and mild chemicals
• Sized for 1/2 inch press fitting connections
• Meets NSF/ANSI 61 standards for contact with potable water systems
• Direct replacement for worn or damaged press fitting O-rings
• No soldering required — compatible with tool-driven press fitting assembly

Compatibility

Designed for use with press fittings requiring a 1/2 inch EPDM O-ring seal. Verify fitting manufacturer specifications before installation to confirm O-ring profile and dimensional compatibility.

Installation Notes

Installation is performed by a licensed plumber or pipefitter using a press fitting tool rated for the fitting system in use. Shut off water supply and depressurize the line before disassembling any fitting. Inspect the fitting seat for scoring or debris before seating the new O-ring. Follow applicable IPC and local plumbing code requirements for press-fit joint assembly and inspection.
