Frequently asked questions
Does this kit provide everything needed for replacement?
Yes, this is a comprehensive kit designed to make servicing straightforward. Each package includes:
- 10 Air valve diaphragms
- 10 Stainless steel screws (#8-32 x 3/8” Soc Hd Button)
- 1 unit of Retaining Compound 609 to ensure all components are secured properly during installation.
Are the diaphragms built to last in demanding environments?
Absolutely. The diaphragms are constructed from high-quality thermoplastic elastomer, a material specifically chosen for its durability and reliable performance during frequent valve operation. Paired with corrosion-resistant 316 stainless steel screws, this kit is engineered to withstand the rigorous demands of sterilization equipment.
Is this a reliable alternative to OEM parts?
The RPI MTK019 is designed as a direct replacement for OEM Part Numbers 78401-261 and 78398-538. RPI components are precision-engineered to meet or exceed original equipment specifications, ensuring seamless integration with your existing system.
Is this kit compatible with MEDIVATORS systems?
Yes, this kit is specifically engineered for use with bulk sterilizers and endoscope processing systems, with primary compatibility for the MEDIVATORS DSD Edge unit.
Are these components used in larger maintenance kits?
Yes, they are. Because of their critical role in system upkeep, these components are also included in the larger RPI preventative maintenance kits, specifically MTK033 and MTK009.
Is a special tool required for installation?
While the kit contains all the necessary replacement parts, RPI recommends using their Low Profile Wrench (RPI Part #RXT003) to facilitate proper installation of the diaphragm assemblies in tight spaces.
Is the stainless steel used in this kit corrosion-resistant?
Yes, the fasteners included in this kit are made from 316 stainless steel. This grade is widely recognized for its superior corrosion resistance, making it an excellent choice for the moisture-heavy environments found in sterilizers and endoscope processors.
Does this package handle multiple maintenance cycles?
Yes. Each package comes with enough components to service 10 valve assemblies. This bulk quantity is ideal for facility managers stocking spare parts or those conducting scheduled maintenance across multiple systems.
Is the included retaining compound necessary for assembly?
Yes, the included Retaining Compound 609 (RPI Part #RXA048) is an essential part of the kit. It ensures that the fasteners and diaphragms remain secure and properly seated, preventing issues with valve function during operation.
Are these parts intended for professional preventative maintenance?
Correct. This kit is specifically curated for use during scheduled preventative maintenance (PM). Using these high-quality RPI replacement parts helps ensure the continued, reliable functionality of the Air Valve Assemblies within your processing equipment.
