Nti 65116896 Seal Washer 0.5 Inch Epdm Dhw

Product Description

The NTI 65116896 is an EPDM seal washer designed for domestic hot water (DHW) plumbing applications. Measuring 0.5 inches in diameter with a 3-millimeter thickness, this washer creates a leak-free seal between fittings and connections in hot water systems. EPDM rubber offers strong resistance to heat and water, making it well suited for the temperature and pressure demands of DHW service. Licensed plumbers and HVAC hydronic technicians install this type of component as part of routine maintenance or system repair work.

This seal washer is used in residential and light commercial plumbing systems where a reliable, watertight connection is required at DHW fittings and unions. It is particularly suited for installations involving NTI boiler and water heating equipment where original-equipment-specification sealing components are required to maintain system integrity and prevent joint failure over time.

Key Features

• EPDM construction provides resistance to heat, water, and common DHW system conditions
• 0.5-inch diameter sized for standard DHW fitting connections
• 3-millimeter thickness delivers consistent compression and sealing force at the joint
• OEM replacement part ensures dimensional accuracy and material compatibility
• Suitable for residential and light commercial DHW applications

Compatibility

Designed as an OEM-style replacement seal washer for NTI domestic hot water systems requiring a 0.5-inch EPDM washer at plumbing connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off the domestic water supply and depressurize the affected line before disassembling any fittings. Inspect the seating surface of the fitting for corrosion or debris before installing the new washer. Do not overtighten the fitting, as excessive force can distort the washer and compromise the seal.
