3 Year Warranty

A $15.90 part still gets the full 4WDetail treatment. Every adapter is machined to lock in solid & hold pressure without leaks, carries a 3 year warranty, & comes backed by the same Brisbane crew who confirm fitments from a single photo. If one ever lets you down, it's a new part in the post: not an argument.

*The fine print (it's short)

The 3 year warranty covers your adapter against defects in materials & workmanship from the day it arrives. Ordered the wrong fitment? That's covered by common sense instead: email help@4wdetail.com with your order number & a photo of your lance end & we'll sort the right one. This warranty is in addition to your rights under the Australian Consumer Law.

Real 4WDers, real fitments. Here's what they reckon.

✦ WHAT REVIEWERS SAY

Reviewers keep coming back to the same things: the adapter fits exactly the washer it's named after, clicks on in seconds, & suddenly the whole 4WDetail range runs on the machine they already own. Plenty also mention ordering the wrong one & having the right fitment sorted quickly by our crew from a single photo.
