$4.56

Official OEM Thermo King parts catalog entry for the Thermo King O-Ring EPDM -113 (334358), verified by PEAK Thermo King and West Texas Thermo King Texas, Utah, Wyoming, Washington, Oregon, serving all of the USA.

Built for Performance: The Thermo King O-Ring EPDM -113 (334358) delivers OEM-grade sealing reliability for Thermo King refrigeration systems, preserving temperature control and preventing refrigerant and coolant loss across demanding transport refrigeration operations.

Product Overview

The Thermo King O-Ring EPDM -113 (part number 334358) provides a durable, elastomeric seal for hose fittings, pump connections, valves, and service ports on reefer trailers and refrigerated trucks. Engineered from EPDM rubber, this O-ring supports consistent temperature control, reduces downtime, and helps fleets maintain fuel-efficient cooling and precise cargo temperatures.

Key Features & Customer Benefits

  • OEM EPDM Material – Delivers resistance to heat, aging, ozone, and weathering for extended service life in outdoor and long-haul conditions.
  • Reliable Seal Integrity – Prevents refrigerant and coolant leaks to preserve system efficiency and reduce unplanned service events.
  • Temperature Range Compatibility – Supports operation across refrigeration temperature cycles, aiding stable temperature control for perishables.
  • Fleet-Proven Durability – Withstands repeated service intervals and road vibration to maintain sealing precision and uptime.
  • Direct Service Fit – Matches common service points on Thermo King units to simplify maintenance and reduce installation time.
  • Environmental Resilience – Resists glycol-based fluids and steam exposure typical of transport refrigeration service environments.

Product Details

Part Number334358
Product NameO-Ring EPDM -113
MaterialEPDM (ethylene propylene diene monomer)
ApplicationSealing hose fittings, valves, and pump connections in Thermo King transport refrigeration systems
Service ContextReefer trailers, refrigerated trucks, and service ports across Thermo King units

Efficiency & Sustainability

By preserving seal integrity, the Thermo King O-Ring EPDM -113 supports fuel-efficient cooling and steady temperature control across refrigerated shipments. Reliable seals reduce refrigerant loss and service frequency, aligning with CARB Evergreen priorities and modern Smart Reefer SR-4 telemetry goals for efficient fleet operation.

Installation & Maintenance Tips

Use OEM-recommended clamps and fittings for secure installations. Inspect O-rings during scheduled service intervals and replace any O-ring showing hardening, cracking, or deformation. Lubricate with manufacturer-approved lubricant to ease installation and prevent pinching. Certified technicians at West Texas Thermo King follow Thermo King service procedures for correct installation and torque specifications.

Real-World Applications

The Thermo King O-Ring EPDM -113 (334358) seals critical connections on reefer trailers, refrigerated box trucks, and diesel direct electric units like S-610DE and Precedent-series equipment. It supports continuous temperature control for food, pharmaceuticals, and temperature-sensitive freight across regional routes and long-haul runs in the Permian Basin and West Texas markets.

Available for installation and service in Amarillo, Lubbock, Odessa, and throughout West Texas.

Frequently Asked Questions

Q: Is this O-ring compatible with Thermo King Precedent and S-610 series units?
A: Yes. The O-Ring EPDM -113 fits common sealing points across Thermo King Precedent and S-610 series systems and supports secure, long-term sealing when installed to OEM service procedures.

Q: What maintenance interval is recommended for O-ring inspection?
A: Inspect O-rings during routine preventative maintenance and at every major service interval; replace any O-ring that shows wear, hardening, or loss of elasticity to maintain temperature control and system efficiency.

Q: Can EPDM handle exposure to coolant and refrigeration fluids?
A: Yes. EPDM provides chemical resistance to water, glycol-based coolants, and many refrigerant service conditions common to transport refrigeration systems.
