Value Collection ZMSCQH70225 O-ring Dash 225 Nbr

Product Description

The VALUE COLLECTION ZMSCQH70225 is a Dash 225 O-ring with an X-profile (quattro) cross section, manufactured from Nitrile Butadiene Rubber (NBR). It measures 1.875 inches inside diameter, 2.125 inches outside diameter, and 0.125 inches thick. The X cross section provides four sealing lobes rather than the single round bead of a standard O-ring, reducing rolling and twisting in dynamic applications while maintaining consistent sealing contact. NBR compound offers solid resistance to petroleum-based fluids, hydraulic oils, and common refrigerants, making this seal suitable across a wide range of fluid-handling and mechanical assemblies. Licensed trades and maintenance technicians install this part as a replacement or service seal.

This O-ring is used in hydraulic systems, pneumatic assemblies, plumbing connections, HVAC refrigerant circuits, and general fluid-sealing applications where a Dash 225 cross-section geometry is required. The X profile is particularly well suited for reciprocating or oscillating sealing surfaces where a standard round O-ring may rotate out of its groove. It is sold in a package quantity of ten, making it practical for service kits and multi-unit repair jobs.

Key Features

• X cross section (quattro profile) resists rolling and twisting in dynamic seal grooves
• Nitrile Butadiene Rubber compound compatible with petroleum oils, hydraulic fluids, and many refrigerants
• Dash 225 standard sizing for drop-in replacement in any Dash 225 groove
• 1.875 inches ID and 2.125 inches OD with 0.125 inch cross-section thickness
• Packaged in quantities of ten to support service kit and fleet maintenance needs

Compatibility

Designed as a standard Dash 225 replacement O-ring for hydraulic, pneumatic, plumbing, and HVAC applications requiring an X-profile cross section in a 1.875 inches ID groove.

Installation Notes

Depressurize and isolate the system before removing the old seal. Clean the groove thoroughly and inspect for wear or damage that could compromise the new seal. Apply a light film of compatible lubricant to the O-ring before installation to seat it evenly and reduce the risk of tearing during assembly. Follow applicable system or equipment manufacturer torque guidelines when reassembling fittings or housings.
