Key Specifications / Parameters Part Number: 21B9340X012 Product Type: Anti‑extrusion ring / backup ring Material: Carbon‑filled PEEK (or similar high‑performance polymer) for elevated temperature/pressure service Application: Prevents extrusion of sealing material (e.g., PTFE seal or soft seat) in the valve trim stack under high differential pressure/temperature service Typical Fitment: Included in parts tables for Fisher ET/EAT valves (e.g., NPS 2 size in some “above 232 °C / 450 °F” service) Service Conditions: Intended for elevated temperature and pressure service where standard backup rings would not suffice Role in Assembly: Positioned just beneath the seal ring (or adjacent to packing) so that when the seal attempts to extrude into a gap, the anti‑extrusion ring blocks that path and maintains seal integrity

Key Specifications / Parameters Part Number: 12B7100X132 Product Type: Gasket Set (includes at least the bonnet gasket and the seat ring gasket) Intended Valve Rating: High pressure (Class 2500) service in the Fisher HP/HPA valve series Material / Construction: The valve manual notes gasket sets for HP/HPA use “N06600/Graphite” for CL1500 and for CL2500 a corresponding set (which the X132 suffix indicates) — thus likely a nickel alloy (e.g., N06600) winding with graphite filler or equivalent high‐performance gasket material Fitment: Typical for valve sizes NPS 1 (as per spare parts table) in the valve series; the table lists 12B7100X132 for “2 (std)” CL2500 valves (globe/angle) for HP and HPA valves Application: When servicing or replacing major sealing surfaces (body/bonnet, seat ring) in HP/HPA valves in demanding service (high pressure, high temperature)

Key Specifications / Parameters Part Number: 29A9221X012 Product Type: Gasket, spiral‑wound, metallic (metal wound + filler) Material: Metal wound (Monel) with silver plating or finish Intended Application: Seat ring or body flange sealing in Fisher EH/EHT series valves for high pressure (Class 2500) service Fitment Example: For 8″ Class 2500 size valves (as listed in aftermarket listings) Description Detail: “Gasket, Monel/Silver Plated, 8″ CL 2500 Type EH” per aftermarket supplier listing
