SMR Series ISO Metric Ring Spacers
Standard PN Designated Ring Spacers
Base Part Number: As shown here, the BASE PART NUMBER defines the Series (three characters), the material (one character), the PN designation, the DN size, and the thickness MM. Replace the PN in the part number with the desired PN designation. For thicknesses up to 150 millimeters, replace the MM with the thickness in millimeters. For thicknesses over 150 mm, contact factory. Note that the PN / DN designation defines the spacer’s dimensions only and does not imply a pressure rating. For example, a PN 10, DN 32 PTFE Ring Spacer x 50 mm thick would be SMRT-10-32-50
1. The OD of the spacers is tangent to the ID of the bolt holes of a similar size full-face flange.
2. Unless otherwise specified by the customer, the spacer’s ID conforms to the ID of the comparable ISO type 01 or type 12 (slip-on) flange.
3. For other options and types of spacers, contact the factory.
