Applications:

NBR soft seal kit enquiries for maintenance of a 4-inch FIG 602 plug valve. Confirm the valve manufacturer, exact model and repair-kit part number before ordering. Nominal valve size and figure designation do not define the dimensions or contents of a replacement set.

Identify the required NBR seals using the valve parts list, drawings or original samples. State the part number, seal profile and quantity for each position. Any PTFE seats, inserts or metal-backed seals should be identified separately with their material and dimensions.

Oilfield application: replacement soft seals for the identified plug valve in the specified equipment. Confirm the valve location and model when the enquiry relates to setting-tool equipment. The kit does not establish a pressure rating for that equipment.

NBR formulation selection: provide the actual oil or fluid composition, operating temperature and pressure. Confirm compatibility for the selected formulation; oil resistance is not a universal rating for every fluid or condition.

Other valve kit configurations — select separately

Support and Services:

1. NBR seal matching: send part numbers and drawings showing inside diameter, outside diameter, section and sealing position. Confirm the required formulation and hardness.

2. Component list: define all seals and any additional seats, inserts or backing parts included. A soft seal kit does not automatically include every overhaul component.

3. Installation: use the valve manufacturer’s maintenance instructions and confirm seal orientation and assembly requirements for the exact model.

4. Custom options: drawings or samples can define replacement profiles and material requirements. Agree tolerances and sample approval before production.

5. Quotation support: provide the valve model, kit identification, quantities and service conditions to help match and quote the required replacement parts.

Confirm the 4-inch FIG 602 valve configuration and the NBR component list before ordering. Valve operating torque and pressure and temperature limits depend on the complete assembly and service conditions.
