NBR 90 Shore Hammer Union Seal Rings for Fig 602 1002 1502 Series

NBR 90 Shore A Hammer Union Seal Rings for FIG 602, 1002 and 1502

This NBR (Buna-N / nitrile) hammer union seal page focuses on a nominal 90 Shore A replacement grade for FIG 602, 1002 and 1502 connections. Confirm the union maker, nominal size and seal profile against the equipment drawing. Include fluid composition, temperature and pressure-cycle conditions with the replacement request.

Product Specification

1. Pressure Requirements: Provide the complete union rating and operating pressure, including transient peaks. Neither a FIG number nor 90 Shore A hardness independently establishes a seal pressure rating.

2. NBR Compound Selection: Identify the process fluid, additives and cleaning chemicals. Review compatibility and temperature limits for the specified nitrile compound rather than treating all NBR grades as interchangeable.

3. Maintenance Fit: Check the replacement profile, sealing faces and pocket dimensions. Follow the equipment maintenance procedure and specify the required assembly inspection and test before reuse.

4. Reference Sizes: Retain the table below as a size and material reference. Select the NBR construction for this page and confirm any brass or stainless anti-extrusion component against the exact assembly drawing.

5. Service Conditions: Define seal acceptance criteria for the actual union assembly. Gas exposure, decompression or sour-service requirements need specific compound qualification and cannot be established by hardness alone.

NBR 90 Shore A Replacement Selection and Inspection

For repeat maintenance orders, provide the existing seal part number, union brand, FIG designation and nominal connection size. Include a dimensioned seal profile or approved sample and the required hardness tolerance. A worn seal should be compared with the equipment drawing before its dimensions are used for manufacture.

Record the conditions seen by the old seal: fluid designation, normal and peak temperature, pressure cycling and cleaning method. Describe cuts, flattening or other visible damage when requesting a replacement review. Include pocket and sealing-face observations so the seal specification can be assessed with the assembly condition.

Specify whether the order includes an anti-extrusion part, its material and its position in the assembly. Keep replacement stock identified by union type, size and compound batch. The other rubber options and swivel kits shown below require separate part identification.
