The Swivel AN Fittings category covers AN swivel-style connectors, typically hose ends and swivel fittings that let you tighten the nut without twisting the hose.
You’ll commonly see straight and elbow options, including 45° and 90°, with AN sizes shown in product names (e.g. AN4–AN12). The range is led by TurboWorks, with Aeromotive and DeatschWerks items also listed.
Use filters (size, angle, brand) and sorting, then open the product card to confirm thread type and hose compatibility. Choose the right swivel fitting and place your order.

Swivel AN Fittings – easier routing, accurate clocking and cleaner plumbing for fuel and oil systems
This category sits under Fuel & Oil Line Fittings and focuses on swivel-style AN parts. The listing shows 72 products with brand filters highlighting TurboWorks as the main range, alongside Aeromotive and DeatschWerks.
A swivel design allows the nut to rotate during tightening, helping you set the final orientation (clocking) while avoiding hose twist. That matters most in tight engine bays where hose strain can lead to leaks over time.
Across the list you’ll find common shapes and sizes referenced directly in product names, such as straight, 45° and 90° versions, and AN sizes like AN4, AN5, AN6, AN8, AN10 and AN12.
Technical Basics
AN sealing relies on the 37° flare seat, so a clean, undamaged sealing surface is essential. The benefit of a swivel nut is that you can tighten without forcing the hose to rotate, which keeps routing neat and reduces torsional stress.
Several items are explicitly listed as hose ends, and TurboWorks product descriptions label them as aluminium connectors intended for oil, water and fuel systems, for use with rubber and nylon hoses.
You will also see naming patterns like “male AN swivel to AN threads” and additional thread markings within titles (for example 9/16-18 or “7/16"-20…”). Treat those markings as compatibility-critical and verify the exact interface on the product card.
Some Aeromotive hose end listings include a note about use on emissions-controlled vehicles, indicating restrictions unless used as an OEM-matching direct replacement. If your vehicle is emissions regulated, read that note before purchase.
Selection Criteria
Start with the line size you already run: choose the matching AN size (for example AN6 for an AN6 system) to avoid stacking adapters. AN sizes are shown in the product names throughout this category, making filtering straightforward.
Next, choose geometry: straight ends work when you have space, while 45° and 90° options help prevent tight bends and improve clearance around bulkheads, radiators and turbo hardware. Aim for smooth hose arcs with minimal side-load on the fitting.
Then confirm hose compatibility: listings for TurboWorks swivel connectors specify rubber and nylon hose use in product details. Match the fitting type to your hose construction before ordering.
Finally, validate threads and interfaces: where a title includes a specific thread marking or transition, that is not interchangeable “by feel”. If you are unsure, select by exact specification rather than forcing an almost-fit connection.
Installation & Maintenance
Work only after depressurising the system and always carry out a full leak check after the first start. Fuel and hot oil leaks are immediate fire risks, so verification is mandatory.
For AN connections, keep the flare seats clean and ensure the nut threads on smoothly. If you need to clock the fitting, position the hose first, then tighten, so the hose does not twist while you chase alignment.
After heat cycles, re-check joints for any weep marks. Typical warning signs are fuel smell, dampness at the nut, or an oil film around the fitting body.
FAQ
Which AN size should I choose for a swivel fitting?
Match the AN size to your existing line, such as AN6 for an AN6 hose setup. Use filters by size, then confirm the exact marking on the product card. Minimising adapters usually reduces potential leak points.
What’s the difference between a hose end and a swivel fitting?
A hose end is designed to terminate and connect a hose, while a swivel fitting can also act as an interface/transition in the line routing. Both can be swivel-style, which helps with clocking and prevents hose twist. Choose based on whether you are finishing a hose or creating a specific routing interface.
Are these for fuel only, or can I use them for oil lines too?
TurboWorks product details in this category describe use for oil, water and fuel systems. You still must confirm hose compatibility and operating conditions for your build. Always verify the specific item’s description before installation.
Do I need thread sealant on AN fittings?
AN seals on the 37° flare, so sealant on the sealing seat is not the standard approach. Where a product involves other thread standards, follow the product-specific assembly guidance. If uncertain, choose the correct interface part rather than relying on sealant to “make it work”.
Why do swivel fittings leak after installation?
Common causes include a dirty/damaged flare seat, hose strain from poor routing, or mismatched threads. Depressurise, re-seat and reassemble carefully, ensuring the hose is not twisted. Then re-test with a focused leak inspection.
Filter by size and angle, confirm compatibility on the product card, then order the right swivel AN fitting for your setup.
