Radiator Tank Gaskets for Kenworth W900/T600/T800 – 1 Pair
Best for: Kenworth W900, T600, and T800 owners needing an exact 40-bolt hole gasket match. This cork rubber seal is built as a 1-pair kit designed to fit specific end-tank configurations. The cork material offers a strong seal with some resistance to heat and compression, making it suitable for standard truck radiator applications. Consider this option if your radiator uses the 40-bolt pattern and you want an authentic fit that aligns with factory specifications.
Why selected: It directly targets the Kenworth models most common in fleets and older builds, reducing the risk of misfit seals. The cork-rubber composition aims to balance sealing with flexibility under heat cycles.
Caution: Confirm your exact bolt-hole pattern before ordering; mismatched holes will compromise the seal.
Radiator Repair Premium Gasket Tape Cork and Rubber
Best for: Quick-field repairs across various radiators and industrial equipment. This cork and rubber gasket tape provides a flexible seal, useful for temporary or emergency fixes when a full gasket kit isn’t available.
Why selected: The long 100-foot length and 1¼-inch width offer economy and coverage for multiple repair sites, making it suitable for shops handling multiple radiators or ongoing maintenance programs.
Limitation: Tape-based seal may not replace a full gasket in all high-pressure, high-heat conditions or long-term replacements; inspect for wear and compression after initial installation.
Radiator Tank Gaskets Compatible with Kenworth W900/T600/T800 (Thick Cork)
Best for: Operators who require a thicker cork seal for enhanced compression resistance and a potentially longer life under demanding operating conditions.
Why selected: The thicker cork material can provide a sturdier seal for engines with harsher thermal cycles or older radiators, helping to reduce the risk of coolant leaks.
Caution: Thicker gaskets can alter bolt alignment slightly; verify the exact end-tank dimensions before replacement to avoid clearance issues.
Radiator Tank Gaskets and Bolt Kit for Peterbilt 357/377/379
Best for: Peterbilt models 357, 377, and 379 with bolt-together radiators needing gasket holes matching the kit’s 42-hole configuration.
Why selected: This kit consolidates gaskets and bolts, simplifying installation for Peterbilt radiator end-tank assemblies and reducing the need for separate fasteners.
Limitation: Ensure compatibility with your radiator’s exact hole layout; Peterbilt models can vary by year and spec, which could affect fitment.
Tearproof Replacement Gasket Seal for Hydraulic Tank Breather Cap
Best for: Hydraulic and oil/fuel reservoir caps requiring a reliable gasket seal beyond radiator-specific applications. Useful for broader machinery maintenance beyond radiators.
Why selected: The three-piece set provides flexibility for multiple caps and ensures a uniform seal across different breather configurations.
Limitation: Not a direct radiator end-tank gasket; use within its intended hydraulic or reservoir cap context to avoid cross-application risks.
Buying Guide — Key Considerations for Radiator End Tank Gaskets
- Compatibility: Match bolt-hole counts and end-tank designs (e.g., 40 vs 42 holes) to avoid misfit and leaks.
- Material: Cork offers a balance of sealing and heat tolerance; cork-rubber blends can improve resilience under cycling conditions.
- Thickness and Compression: Thicker gaskets can endure higher compression but may affect bolt alignment; verify OEM or universal fit recommendations.
- Application scope: Some gaskets cover specific truck models; others serve broader radiator or hydraulic cap needs. Choose based on the primary equipment in your fleet.
- Installation: Some kits include bolts; if not, ensure you have the correct hardware to secure the end-tank assembly.
Frequently Asked Questions
- Q: How do I know which gasket material is right for my radiator? A: Consider operating temperatures, coolant types, and the end-tank design. Cork and cork-rubber blends work well in standard truck radiators, while higher-heat systems may benefit from thicker or reinforced seals.
- Q: What does bolt-hole count indicate? A: It specifies how many holes the gasket matches. Using the wrong count can cause leaks or improper seating.
- Q: Can I reuse a gasket? A: Reuse is not recommended for end-tank gaskets due to sealing degradation under heat and pressure. Replace during radiator service.
- Q: Are these gaskets compatible with all Kenworth and Peterbilt models? A: Compatibility depends on the exact model and year. Always verify bolt pattern and end-tank dimensions before purchasing.
- Q: Do gasket kits include bolts? A: Some kits include bolts; others require separate hardware. Check the product listing for included components.
- Q: Is a gasket tape a good replacement for a full gasket kit? A: Gasket tape is useful for quick repairs or temporary fixes, but it is not a full substitute for a proper gasket in high-pressure, long-term applications.
