Replaceable O-Ring Kit - Nilfisk

The set includes 10 O-rings, featuring five common types used in Nilfisk Consumer High-Pressure Washers, along with silicone grease for lubrication and sealing.

This kit is designed for Nilfisk Consumer High-Pressure Washer (HPW) models and is compatible with accessories like the lance, spray handle, water inlet coupling, and high-pressure hose.

O-rings should be replaced when they show signs of wear, damage, or when you notice leaks at connection points. Regular inspection is recommended, especially if you use your pressure washer frequently.

No, this O-ring set is specifically designed and tested for Nilfisk Consumer HPW models only. Using it on other brands may not provide a proper seal and could cause damage.

The silicone grease helps to lubricate the O-ring, making it easier to install and preventing it from binding or tearing. It also aids in creating a better, more durable seal.

The reference number for this Nilfisk O-Ring Set is 128500292.

Ensure the correct O-ring size was used. Verify that the O-ring is seated properly in its groove and that no debris is present. Reapply a small amount of silicone grease and re-tighten the connection firmly but without overtightening.

Apply a little more silicone grease to the O-ring and the groove. Ensure you are not trying to fit it into an incorrect or damaged recess. If the O-ring feels forced, double-check compatibility and the seating area.

Check for any damage to the fitting itself, not just the O-ring. Ensure the O-ring is not twisted or pinched. Make sure the connection is aligned correctly before attempting to secure it.
