Dimensions you can trust

The N40HLC measures approximately 3.07 inches (78 mm) in length and 1.58 inches (40 mm) in width. These dimensions are important for ensuring a proper fit, especially if you’re comparing to the N40HKC variant. If your fixture’s exact model differs, verify compatibility to avoid a mismatched fit.

• Length: 3.07 inches (78 mm)
• Width: 1.58 inches (40 mm)
• Note: specs may differ from N40HKC—check your model before replacement

Temperature stability and safety

One of the key design goals is consistent water temperature as pressures shift. The cartridge helps maintain steady mix conditions, and in the unlikely event of a sudden cold-water interruption, the faucet output may stop promptly for added safety and convenience.

• Stabilizes temperature despite pressure fluctuations
• Designed to minimize abrupt temperature changes
• Quick response in cold-water supply interruptions

Materials and durability

Crafted with a ceramic core and durable plastic housing, the N40HLC emphasizes reliable seals and long-term performance. The ceramic core is noted for resistance to both high temperatures and wear, contributing to endurance in regular use.

• Ceramic core for wear resistance and temperature tolerance
• Quality seals help reduce leakage over time
• Combination of ceramics and high-quality plastic for durability

Easy DIY installation

Install this cartridge with minimal tools and effort. Remove the old part, wipe away debris, and slide the N40HLC into place. The straightforward swap can save time and avoid the need for a professional repair visit.
