ROADFORMER 6" T-Bolt Hose Clamp 158–166mm (6") 2-Pack — 304 SS Band, Nylon Locknut for High-Pressure Marine & Automotive

ROADFORMER 6" T-bolt hose clamp is a heavy-duty 304 stainless steel clamp sized for hoses with 158–166mm (6.22"–6.54") outer diameter, supplied as a convenient 2-pack for reliable, leak-resistant connections.

Built for high-pressure and demanding environments, this T-bolt clamp combines a 3/4" 304 stainless steel band, a 300-series stainless bolt (1/4"-28), a floating bridge and a nylon-insert locknut to hold a steady, uniform clamping force. It fits nominal 6" ID hoses (measured by outer diameter 158mm–166mm) and works across automotive, marine, industrial, off-road and agricultural applications where a durable, corrosion-resistant clamp is required. Check your hose outer diameter and wall thickness (recommended 3–6mm) before ordering to ensure the clamp will tighten properly without over-compressing thin walls or failing to engage on overly thick hose walls.

How does this clamp achieve a leak-resistant seal?

The ROADFORMER T-bolt design distributes pressure evenly around the hose circumference using a wide 3/4" band and a floating bridge that prevents local pinching. The nylon-insert locknut resists vibration loosening, while the stainless materials reduce corrosion and maintain consistent torque over time.

• Wide 3/4" 304 stainless band for even compression
• Floating bridge prevents band distortion and hose damage
• Nylon-insert locknut retains torque under vibration
• 300-series SS bolt resists rust for long-term sealing

Will this clamp fit my hose and how should I measure?

Measure the hose outer diameter (O.D.) where the clamp will sit, not the inner diameter (I.D.). This ROADFORMER clamp is intended to tighten from approximately 158mm to 166mm (6.22"–6.54"), matching common 6" nominal hoses; confirm your hose wall thickness is within the recommended 3–6mm range for best results.

• Measure hose O.D. with calipers or tape for accuracy
• Compare measured O.D. to the clamp's 158–166mm working range
• Avoid thin-walled hoses that can crimp under high torque
• Check for fittings, beads or ridges that may affect fit

What tools and steps are needed for installation?

Installation is straightforward: slide the clamp over the hose, position it over the fitting or barb, align the bolt and tighten with a wrench or socket until the clamp firmly compresses the hose without over-tightening. The design allows common hand tools to reach the bolt and achieve the required torque without specialized equipment.

• Tools: 3/8" or appropriate socket, or a hand wrench
• Step 1: Slide clamp onto hose before assembly
• Step 2: Seat hose fully on the fitting or barb
• Step 3: Tighten until secure, avoid excessive torque

How durable is the clamp in harsh environments?

Constructed from Type 304 stainless steel for the band and a 300-series stainless bolt, the clamp resists corrosion in wet, salty or dirty conditions. The locking nut and robust bridge design maintain clamping force through vibration and thermal cycling, making it suitable for extended use in demanding settings.

• 304 stainless resists rust in marine and road conditions
• Floating bridge reduces fatigue and band deformation
• Nylon locknut minimizes loosening from vibration
• Designed for repeated tightening without losing performance

Who is this for: Professionals and DIYers who need a dependable, corrosion-resistant clamp for 6" nominal hoses—mechanics, marine technicians, farm equipment operators, off-road builders and industrial maintenance crews. Choose this 2-pack when you want a durable, easy-to-install solution that holds torque, prevents leaks and endures harsh operating conditions. Remember to verify your hose outer diameter and wall thickness against the clamp's working range before purchase to ensure proper fit and long-term reliability.
