ORM O-Ring 0250-40, NBR - 25mm ID x 4mm Thick
A standard NBR (nitrile) O-ring, 4.0 mm cross-section with a 25.00 mm internal diameter, a common size used throughout espresso machine group seals, valve bodies, and fittings.
SPECIFICATIONS
- 4.0 mm thickness
- 25.00 mm internal diameter
- NBR (nitrile rubber) compound
COMPATIBILITY
- Works with: group heads, valves, and fittings sized for this O-ring, check your machine's exploded parts diagram for this dimension before ordering
INSTALLATION
Simple DIY replacement, lightly lubricate with food-safe silicone grease before seating to ease installation and extend seal life.
PRO TIPS
- NBR is a solid all-around choice for water-side seals, but if the O-ring sits near direct steam or sustained high heat, check whether your machine calls for a silicone or EPDM equivalent instead, NBR degrades faster under prolonged heat exposure.
