Danco 35751B Buna-n O-ring 1-11/16 X 1-7/8 in Faucet Seal

Product Description

The DANCO 35751B is a Buna-N rubber O-ring sized at 1-11/16 inches by 1-7/8 inches, designed for faucet repair and general plumbing sealing applications. Buna-N (nitrile) rubber is a standard material choice for water-service seals due to its resistance to abrasion, compression set, and water swell. This O-ring maintains a reliable static or dynamic seal in wet environments and is sold individually. Plumbers and service techs keep a range of O-ring sizes on hand for quick faucet rebuilds, valve repacking, and fixture maintenance calls.

This O-ring is suited for residential and light commercial plumbing service work. Common applications include faucet cartridge replacement, valve stem sealing, and general fixture repair where a Buna-N O-ring of this cross-section and inner diameter is required. It ships in a single-piece bag, making it easy to stock individually or in multiples for service kits.

Compatibility

Designed as an OEM-style replacement or service O-ring for faucets, valves, and plumbing fixtures requiring a Buna-N seal at the 1-11/16 inches by 1-7/8 inches dimension.

Installation Notes

Licensed plumbers and experienced DIYers typically install O-rings of this type during faucet rebuilds or valve repacking. Shut off the water supply and relieve line pressure before disassembling any faucet or valve. Lightly lubricate the O-ring with a plumber-grade silicone grease before seating to prevent tearing during assembly. Avoid petroleum-based lubricants, which can degrade Buna-N rubber over time.
