Frequently asked questions
Is this washer compatible with Midmark-Ritter Model 7 units?
Yes, the RPI RCW009 is specifically designed for the Door Assembly (T-Bolt) of MIDMARK - RITTER Model 7 sterilizers.
Does the nickel plating provide added durability?
Absolutely. The washer is constructed from copper with a nickel-plated finish. This combination provides enhanced corrosion resistance and longevity, which is crucial for the high-heat and moisture-heavy environments found inside autoclaves and sterilizers.
Does this part replace specific OEM components?
Yes, this is an exact cross-reference for OEM Part #H96771 and OEM Part #3059. It ensures you are getting a replacement component that meets the original manufacturer’s specifications for your equipment.
Does this washer meet precise dimensional requirements?
Precision is vital for sealing mechanisms. This component features exact dimensions of 0.375” ID x 0.635” OD x 0.090” THK, ensuring a secure and reliable fit for your door assembly.
Is this a brand-new component?
Yes, all units are supplied in Factory New condition. This guarantees that you are receiving an unused, high-quality part for your maintenance needs.
When is the best time to replace this washer?
It is highly recommended to replace this washer during scheduled maintenance or repairs of your sterilizer’s door sealing mechanisms. Replacing worn seals helps maintain the integrity of your sterilization cycles.
Is this specifically for the T-Bolt door assembly?
Yes, this washer is engineered for use in the Door Assembly (T-Bolt). It is a critical component for maintaining the correct seal pressure in your MIDMARK - RITTER Model 7 unit.
Can I rely on this for autoclave maintenance?
Definitely. As an RPI-manufactured part, this washer is built to meet strict standards for medical and laboratory equipment, making it a dependable choice for your maintenance requirements.
Why is copper used for this washer?
Copper is widely used in these high-pressure, high-heat applications because of its excellent thermal conductivity and malleability, allowing it to form a superior seal when tightened within the door assembly. The addition of the nickel plating further protects the copper from degradation over time.
Can I expect a perfect fit with these measurements?
Yes. Because this washer is manufactured to specific tolerances—0.375” ID x 0.635” OD x 0.090” THK—it is designed to provide the exact fitment required for the specified Midmark-Ritter sterilizer models, minimizing the risk of leaks or installation issues.
