HNeekyr 6AN Transmission Cooler Hose Kit 52" - Stainless PTFE Braided, 2-Pack with Swivel Elbows

HNeekyr 6AN 52" Transmission Cooler Hose Line Kit is a stainless‑steel braided PTFE transmission cooler hose assembly with 6AN fittings and multiple NPT adapters designed to add reliable cooling lines to a wide range of automatic transmissions.

This kit delivers a ready‑to‑install solution for routing transmission fluid through an external cooler. Built from PTFE tubing wrapped in stainless‑steel braid, it resists corrosion, high temperatures and abrasion while the included 6AN fittings and assorted adapters make it compatible with many legacy and modern transmissions. The package includes two 52" hoses and a set of swivel elbows and adapters so you can configure lines for both inlet and outlet connections without extra parts.

What transmissions will this cooler hose kit fit?

The HNeekyr kit is engineered for broad compatibility with common automatic transmissions. It supports GM Turbo 350, Turbo 400, Turbo 200/200R4 families, Power Glide, 700R4 and the 4L60/4L60E/4L65E/4L80E series, plus many Ford C4, C6 and AOD applications. Compatibility is achieved through the included 6AN fittings and multiple NPT adapters so you can match factory ports.

• Fits Turbo 350 with 1/4" NPT and Turbo 400 series
• Supports 200R4, 700R4 and 4L60/4L80E families
• Works with Power Glide and Ford C4/C6/AOD setups
• Adapters: 6AN to 1/4" NPT and 3/8" NPT included

How does the construction improve durability and leak resistance?

The hose uses PTFE inner tubing for chemical compatibility with transmission fluids, wrapped in stainless‑steel woven wire to stop chafing and resist heat. That combination reduces the chance of swelling, cracking or abrasion over time compared with rubber lines. Swivel elbow fittings and properly sized adapters also help prevent stress and leakage at connection points.

• PTFE core resists fluid degradation and high temperatures
• Stainless steel braid protects against abrasion and cuts
• Swivel 90° elbow fittings ease installation and reduce torsion
• Multiple adapters ensure tight, secure connections

What’s included and how simple is installation?

The kit arrives with everything needed for a typical two‑line installation: two 52" braided hoses, two 90° swivel 6AN fittings, and four 6AN to 1/4" NPT plus two 6AN to 3/8" NPT adapters. Installation is straightforward for anyone comfortable with basic hand tools and drip management—no specialized hydraulic equipment required. Use thread sealant where appropriate and follow torque specs to avoid over‑tightening fittings.

• 2× 52" PTFE stainless braided hoses, 3/8" ID
• 2× 90° female‑to‑male swivel 6AN elbows
• 4× 6AN→1/4" NPT adapters and 2× 6AN→3/8" NPT adapters
• Designed for straightforward swap or aftermarket cooler add‑ons

Who is this for: The HNeekyr 6AN 52" Transmission Cooler Hose Line Kit is aimed at mechanics, DIY truck and SUV owners, and restoration shops that need durable, universal transmission cooling lines. It’s a good match when replacing aging rubber lines, adding an auxiliary cooler, or re‑routing fluid lines in custom applications. If you want corrosion‑resistant hoses with flexible fitting options to match classic and modern automatic transmissions, this kit provides a practical, ready‑to‑install set of components.
