FKM Hammer Union Seals 1-4 Inch for Oil and Gas Industry

FKM Hammer Union Seals for 1–4 Inch Nominal Connections

This FKM hammer union seal listing provides a starting point for replacement enquiries across the listed 1–4 inch nominal connection sizes. Match each seal to the union manufacturer, FIG designation and equipment drawing. The connection size identifies the assembly and must be accompanied by the actual seal profile and compound specification.

Product Specification

1. Assembly Rating: Provide the union rating and operating pressure with pressure-cycle conditions. Neither nominal connection size nor FIG number establishes a separate elastomer-seal pressure rating.

2. FKM Specification: Identify the fluid composition, additives, cleaning agents and normal and peak temperatures. Review those conditions against the selected FKM compound before approving a replacement.

3. Dimensional Fit: Check the seal section, sealing faces and pocket dimensions against the equipment drawing. Follow the union maker’s maintenance procedure and verify the assembly after replacement.

4. Size Identification: The retained table lists individual nominal sizes and material references. Confirm the FIG and seal construction for each size, including any brass or stainless anti-extrusion part.

5. Operating Qualification: Define assembly inspection and test requirements for the service. Gas, sour-service or decompression conditions require specific qualification for the selected compound.

Build a Size-Specific FKM Union Seal Order

For an order covering multiple connection sizes, list each seal as a separate line with union brand, FIG number, nominal size, seal part number and quantity. Include the drawing revision for each line so the 1, 2, 3 and 4 inch references are matched to their own seal geometry.

Specify the FKM compound, one nominal hardness and its tolerance for each required part. Where service conditions differ between lines, give the fluid and temperature details separately. Confirm any anti-extrusion component and whether the quotation covers the elastomer alone or the specified combined construction.

Agree the part identification, dimensional checks and required documents before sample approval or repeat purchase. Use the size table below as a reference rather than a substitute for the assembly drawing. The additional 1-1/2 inch and FIG 206 entries require their own confirmed part specification.
