Narrow Copper Washer for 1/4" Fittings
Dimension-specific copper sealing washer for La San Marco 1/4" fitting connections, sized smaller in both bore and outside diameter than the common C_129 and MZ_25 washers, easy to grab the wrong one if you're not measuring first. Copper deforms slightly under torque to create a reliable metal-to-metal seal at group and boiler fittings.
SPECIFICATIONS
- Dimensions: 18 x 13.5 x 1.5 mm
- Material: copper
COMPATIBILITY
- Fits: La San Marco 1/4" fitting connections
- Replaces: La San Marco CPCRON0250 (204059)
INSTALLATION
Simple DIY swap, just make sure the old washer is fully cleared before seating a fresh one.
PRO TIPS
- Copper washers work-harden after their first heat cycle, so reusing an old one instead of installing a fresh one is one of the most common causes of a "mystery" weep right after a fitting was just serviced, always replace, don't reuse.
- This washer is deliberately smaller than the C_129 and MZ_25, if you're not certain which size your machine uses, measure the old one before ordering rather than guessing from a diagram.
