EVIL ENERGY 12AN Hose End Fitting Straight Swivel
Best for: Users with stainless steel braided or nylon braided hoses who need a straight, swiveling connection. Why: This 12AN straight swivel uses a 6061-T6 aluminum body and a 37-degree sealed AN side to maintain a reliable seal under high pressure. The fitment is compatible with the intended hose types and reduces hose twist during installation. Note: The thread size is 1 1/16-12 UNF, so verify hose compatibility before purchase.
EVIL ENERGY 12AN Flare to AN12 ORB Male Fitting Adapter
Best for: Projects needing an adaptable flare-to-ORB interface. Why: This adapter combines a 12AN flare sealed by a 37-degree angle with an ORB‑sealed O‑ring side, constructed from 6061-T6 aluminum with an NBR O‑ring. It’s suitable for setups where both flare and ORB seals are required, but ensure compatibility with your hose type. Caution: If only a single seal is used, leaks may occur at high pressure.
EVIL ENERGY 12AN 90 Degree Push Lock End
Best for: Tight spaces where a 90-degree route is needed with braided hoses. Why: The 12AN end threads at 1 1/16-12 UNF and the barb end fits 3/4″ rubber fuel lines, with a maximum working pressure around 1,500 PSI and a wide temperature range from -40°F to 248°F. Caution: Only compatible with rubber fuel lines on the barb side; not ideal for non-rubber hoses.
EVIL ENERGY 12AN Hose End Fitting 90 Degree Swivel
Best for: Applications needing a 90-degree turn with stainless or nylon braided hoses. Why: This 12AN to 3/4″ barb swivel features a 1 1/16-12 UNF thread and a durable aluminum 6061-T6 body. It’s a good choice when you require a compact elbow connection that resists wear. Caution: Confirm hose material compatibility; some fuel lines may not work with the barb connection.
EVIL ENERGY 12AN Straight Push Lock End
Best for: Direct 12AN to 3/4″ barb connections in constrained spaces. Why: The 12AN end uses 1-1/16-12 UNF threads with a push‑lock mechanism and a 1,500 PSI working pressure rating, suitable for rubber fuel lines in high‑pressure lines. Caution: Push‑lock fittings may require compatible hose cuff dimensions for a secure seal.
EVIL ENERGY 12AN Straight Push Lock End (Another Option)
Best for: Additional direct 12AN to 3/4″ barb connection needs. Why: Similar specification with 1-1/16-12 UNF thread and a 1,500 PSI rating under a rubber hose regime. Caution: Check the exact barb size in your hose kit to ensure a proper fit.
Buying Guide
What should you check before buying 12AN fittings?
- Thread compatibility: Most 12AN fittings use 1 1/16-12 UNF. Verify your hose end and adapter threads match to avoid leaks.
- Seal type: Options include flare (37-degree), ORB with O‑ring, and push‑lock. Choose based on hose type and required sealing method.
- Material and finish: Aluminum 6061-T6 is common for strength and corrosion resistance. Anodized finishes add durability for harsh environments.
- Hose compatibility: Some fittings are designed for stainless or nylon braided hoses, others for rubber fuel lines. Use the correct combo to prevent damage or failure.
- Pressure and temperature: Check maximum working pressure and operating temperature ranges to ensure suitability for your system.
- Space and routing: 90-degree fittings are useful in tight spaces; consider swivel options to reduce line tension and wear.
Frequently Asked Questions
- What does 12AN mean?
12AN refers to a 12‑inch nominal AN thread used in high‑pressure fluid connections in automotive and performance applications. - Can I mix 12AN with different seals?
Yes, but ensure the seal type matches your hose and operating conditions to avoid leaks. - Which hose types work with 12AN fittings?
Most fittings are designed for stainless or nylon braided hoses and sometimes rubber fuel lines with compatible barbs and adapters. - Are 90-degree fittings prone to leaks?
Leak risk is minimal when properly matched, torqued, and sealed using the correct O‑rings or seals for the hose type. - What is the advantage of a swivel fitting?
Swivel fittings reduce hose twist and ease install in tight spaces, improving longevity of the connection. - Should I choose an adapter with ORB or a flare seal?
ORB seals are common for complex assemblies; flare seals are standard for many automotive lines. Choose based on your hose and system requirements.
