Set of OR-3-D O-rings for FP3 systems, designed for housings of series H10A, H10B, H10C, H10D, and H10K. The set includes seals: OR-N-880x40 and OR-N-900x35. Included for free is a special grease for lubricating the seals, which facilitates installation and improves the performance of the seals.
ORING OR-3-D is a complete seal kit designed for FP3 systems, used as consumable components in solutions such as a water filter, water filtration system, or reverse osmosis system. The set fits housings from the H10A, H10B, H10C, H10D, and H10K series and includes two O-rings marked OR-N-880x40 and OR-N-900x35. The комплект also includes a special grease for lubricating seals, which makes installation easier, supports proper seating of the O-rings, and improves seal performance.

The OR-3-D set has been prepared for FP3 systems. It is a practical sealing kit that helps maintain proper tightness of connections in filter housings and supports safe system operation.
The product is intended for housings from the series:
As a result, the set works wherever proper seal performance matters in installations related to water filtration and treatment.
The set includes all elements listed for the OR-3-D kit:
The inclusion of mounting grease is a practical benefit during seal replacement. Lubrication helps reduce the risk of the O-ring folding during installation, makes assembly easier, and supports even seal operation.
O-rings are small but very important components of any filtration system. They are responsible for the tightness of connections between housing parts and affect the stable operation of the entire system. A worn, flattened, or improperly seated seal can lead to fitting problems and leaks.
Replacing the seal set with the correct kit matched to FP3 systems and H10A-H10K series housings helps restore proper sealing and makes further operation of the installation easier.
To achieve proper sealing, it is worth cleaning the seal grooves before installation and checking that the contact surfaces are free of dirt and damage. O-rings should be seated carefully, without excessive stretching or twisting.
Before closing the housing, it is recommended to use the included special grease for lubricating seals. A thin layer of the product makes it easier to position the O-ring correctly, supports installation, and improves seal performance during use.
Regular inspection of seal condition is a good part of servicing systems such as an osmosis filter, reverse osmosis filter, or other water treatment solutions. In the event of visible wear, deformation, or sealing issues, it is worth replacing the complete set with a new one.
