Earl's Performance UltraPro 45° Crimp-On Wiggins Quick-Disconnect Hose Ends

Earl's Performance UltraPro Series 45-degree crimp-on Wiggins quick-disconnect hose ends bring aviation-grade fluid transfer technology to high-performance automotive, racing, and industrial plumbing systems. Engineered exclusively for use with Earl's UltraPro Series hose, these fittings form a fully matched, optimized plumbing system built to withstand the most demanding conditions on the track or street.

Premium Materials and Construction:

• Ultra high-strength 2024-T8 aluminum in all high-stress components — a significant upgrade over the 6061-T6 aluminum found in competing products
• Furnace-brazed bent tube construction creates a permanent, robust bond throughout the fitting body for unmatched strength and unrestricted flow
• Fluoroelastomer internal seals provide outstanding chemical resistance to fuels, oils, coolants, and hydraulic fluids
• Lightweight design eliminates unnecessary mass without compromising structural integrity
• Select hose ends feature Dynamic Swivel™ technology, allowing 360 degrees of post-installation rotation for easier hose routing and service

Wiggins Quick-Disconnect Technology:

• Threadless male and female designs allow smooth, effortless tool-free connection and disconnection
• Coupled by a threadless clamshell closure (sold separately) manufactured by Adel Wiggins — the industry leader in aviation quick-disconnect technology
• 45-degree angled body improves hose routing flexibility in tight or complex plumbing environments
• Crimp-on attachment method creates a secure, permanent bond between the fitting and hose
• Engineered to withstand repeated connection cycles while maintaining a consistent, leak-free seal

Mil-Spec Finish and Sealing:

• Hard anodized to Mil-Spec III Class 1 standards with exclusive PTFE impregnation to reduce fluid flow friction and improve long-term durability
• Male ends include plasma-coated nitrile O-rings pre-installed for extended service life
• Finish is engineered to withstand harsh underhood environments and aggressive fluid exposure

System-Matched Performance:

• Designed as a complete system exclusively matched to Earl's UltraPro Series hose for optimized, leak-free performance
• Available in both male and female Wiggins quick-disconnect configurations across multiple AN sizes
• Suitable for racing, high-performance street, and demanding industrial fluid transfer applications

Backed by decades of Earl's engineering heritage — a legacy built on bringing military aircraft plumbing technology directly to the racing market — the UltraPro Wiggins quick-disconnect hose end line represents the pinnacle of performance plumbing. Note: All UltraPro hose assemblies must be pressure tested prior to use. Crimp-on hose ends require the Earl's crimping machine and appropriate crimp die (sold separately).
