- • Best for: DIY mechanics and workshop technicians needing fast on-spec testing and cooler-line swaps
- • Not ideal for: Users who have not verified exact port measurements or who need guaranteed OEM-spec parts
Two precision-machined aluminium adapter fittings, supplied with two rubber O-rings, are sized for front and rear 4L80E ports. Designed for straightforward installation and to withstand high-pressure cooler line environments.
Secure, leak-resistant connections - with precision-machined threads and rubber O-rings
Threads are machined to tight tolerances to match flare and NPS fittings while rubber O-rings create a compressible seal at the joint. The combination reduces gaps where fluid could escape under pressure.
A reliably tight connection minimises the risk of transmission fluid leaks during operation and testing, helping avoid messy rework.
Durable under pressure - thanks to premium aluminium alloy construction
Aluminium alloy provides a high strength-to-weight ratio and resists deformation under load, suitable for high-pressure transmission cooler environments. The material selection supports repeated install and removal without cracking.
Longer service life and fewer replacements make workshop jobs more dependable, especially when testing or diagnosing cooler-line issues.
Fast workshop swaps - with included pair, distinct lengths and no extra tools required
The set includes a longer rear fitting and a shorter front fitting with specified dimensions, allowing direct replacement of corresponding ports. Install design is straightforward so extra tools are not necessary for most swaps.
Quicker turnaround for repairs and on-spec testing, saving time during diagnostics and reducing vehicle downtime.
