ETZ 2 Inches Fuel Tank Strap Isolator
The ETZ fuel tank strap isolator is a six-foot-long, two-inch-wide rubber block designed to fix fuel tanks securely on most semi-trailer trucks. The heavy-duty rubber offers wear resistance, corrosion protection, and insulation to reduce friction between the strap and the tank. Best for fleets prioritizing durable, long-lasting isolation and straightforward installation. A potential limitation is compatibility with non-standard strap widths beyond 2 inches.
Best for: fleets needing a simple, durable isolator that reduces metal-to-tank contact and dampens vibration. Choose this if you value long service life and corrosion resistance in varied weather conditions.
Mytee Viking 68″ x 80″ Rack Kit with 50 Gal Fuel Tank
This kit includes a Viking Day Cab Rack (68″ x 80″) with a bar window and two chain hangers, plus a 50-gallon aluminum fuel transfer tank. It’s best for operators who want an integrated storage and fueling solution for semi-trucks, trailers, and diesel transport. Limitations include the need for compatible mounting space and potential increased vehicle height due to rack and tank assembly.
Best for: buyers seeking a combined storage and transfer solution that adds fuel capacity and organized chain storage on day cabs or larger trailers. Avoid if you need only straps or isolators without ancillary racks or transfer tanks.
Mytee Products SMR30S 30 Gallon Saddle Mount Tank
The SMR30S is a 30-gallon saddle-mount hydraulic tank replacement option, designed for dump trucks, trailers, and semi configurations. It features a saddle mount design, a black powder-coated finish, and compatibility with multiple OE aftermarket parts. Use this when a hydraulic system requires an auxiliary fuel or hydraulic oil reservoir with a robust mounting solution. A note: verify mounting brackets and space in your specific rig before purchase.
Best for: users needing a durable auxiliary tank that integrates with existing hydraulic or fuel systems on heavy-duty trailers. Better for installations where a side-mount or saddle-mount configuration is already planned.
RDS MFG rectangular 69 Gallon Auxiliary Fuel Tank
RDS MFG INC offers a rectangular auxiliary fuel tank with a 69-gallon capacity. It accommodates various capacities and dimensions to fit different rigs, and allows gasoline fueling with an electric pump. This selection suits operators needing an additional fuel source for extended runs or multi-stop routes. A possible limitation is the need for proper top-fueling access and a secure mounting layout to prevent movement.
Best for: fleets needing an additional fuel reservoir on semi-trailers or tank trucks with flexible dimensions. Better for applications where gasoline-compatible fueling and top-access pumping are advantageous.
Aomitop 2 Inches Seal for Fuel Tank Strap Isolator
This is a replacement seal compatible with fuel tank strap isolators, measuring six feet long and two inches wide. It’s designed for heavy-duty semi trucks and emphasizes durability with robust materials. Best for adding or replacing isolator seals to maintain secure fuel tank mounting. Limitation: product description focuses on seals and not full isolator assemblies, so verify compatibility with your strap model.
PIHIL 3 Inch Fuel Tank Straps Isolator
The PIHIL isolator uses a wider three-inch strap interface and six-foot length, intended for heavy-duty semi trailer trucks. It’s crafted from durable rubber to resist cracking and weathering while maintaining a secure fit amid road vibrations. Best for trailers that require wider strap isolation or higher load-bearing capacity. Limitation: higher-profile isolator may require clearance checks on some trailers.
Ulreon 4 Inch Fuel Tank Strap Isolator
The Ulreon isolator accommodates four-inch strap applications and is designed to reduce vibration-induced noise. It emphasizes universal compatibility with semi-trailer trucks, tank trucks, and trailers, plus enhanced anti-wear protection to extend tank lifespan. A caution: verify strap width compatibility and ensure the mounting area can accommodate a 4-inch isolator in your vehicle design.
2 Pcs 2 Inches Seal for Fuel Tank Strap Isolator
This product offers a two-pack of seals for fuel tank strap isolators, measuring six feet long and two inches wide each. It’s useful for replenishing seals in fleets with multiple semi-trailers or for replacement parts across several vehicles. Best for budget-conscious buyers needing consistent seal replacements. Limitation: seals are a component piece and do not include the full isolator assembly.
Buying Guide
What should I consider when choosing a fuel tank strap isolator?
Key factors include strap width compatibility, material durability (rubber quality and resistance to oils), length to fit your trailer layout, and resistance to weather conditions. Choose products with corrosion resistance and vibration damping to minimize wear on the tank and mounting hardware.
Which isolator is best for heavy vibration environments?
Rubber isolators designed for heavy-duty use and higher strap widths (3-4 inches) tend to perform better under constant road vibrations. They reduce noise and protect the tank-tank strap interface from direct metal contact.
Should I prefer an integrated tank or a standalone isolator?
Integrated options (such as auxiliary tanks with racks) suit fleets needing additional fuel capacity and storage. Standalone isolators work well when you only need secure mounting without extra storage components.
What space and mounting considerations matter?
Check clearance for strap width, the overall height added by the isolator, and whether your trailer has enough room for larger four-inch isolators. Ensure mounting brackets align with tank positions and strap anchors.
Are there compatibility concerns with different trailer brands?
Most isolators are designed for standard semi-trailer dimensions. Verify compatibility with your truck model, strap type, and whether you need average or wide-width inserts for safe operation.
How do I maintain fuel tank components?
Regularly inspect seals and the surface of straps and isolators for cracking, wear, or corrosion. Replace worn components promptly to prevent fuel leaks or tank movement during transit.
Careful questions to ask when buying
- What strap width does the isolator support?
- Is the material resistant to oil and road salt?
- Will the product fit my trailer’s mounting points and height allowances?
- Does the kit include seals or only the isolator body?
FAQ
Q1: Are fuel tank strap isolators universal across all semi-trailers?
A1: Most isolators fit a range of standard semi-trailer trucks, but always check strap width and mounting dimensions for compatibility.
Q2: Can I replace just the seal without replacing the isolator?
A2: Yes, some products offer seals or packs designed to replace worn seals while keeping existing isolators in service.
Q3: Do four-inch isolators fit all trailers?
A3: Four-inch isolators fit many heavy-duty trailers but may require additional clearance checks for specific models.
Q4: Is an integrated fuel tank kit better than separate parts?
A4: It depends on goals. Integrated kits provide storage and fueling options alongside mounting, while standalone isolators focus on securing the fuel tank with minimal additions.
Q5: How important is anti-corrosion material?
A5: Important for durability in any climate, especially in areas using road salt or humid environments. Look for corrosion-resistant rubber or protective coatings.
