Flexible Coupling - 4.0" x 6.0" - White

I was installing an outdoor radon system with white pvc pipe. The fan was six inches and I used four inch schedule 40 pvc pipe. I coupling fit nice and tight. No problem with the product.

I should have slowed down when ordering this as when I glanced at the picture I thought it came in a pair just as many other websites. It makes sense to sell them in pairs as you need two for a radon fan install offer. Well off to order another one. Maybe the seller should change the main pick so it only shows one coupling instead of two.

This coupling is too small for the 6" fan (RP265). Inner diameter of this product is smaller (1-2 mm) than the outer diameter of the fan. I will attach a photo as an update.

ok

This coupling is well constructed from quality materials. However, the photo provided is somewhat misleading. For each quantity ordered, you only receive ONE coupling.

NOT A TRUE 4" x 6" Adapter. Pay attention to dimensions in questions. It is described as an adapter from 4" to 6" but it will not actually fit onto a 6" outside diameter pipe.

Radon mitigation project picture shows 2 couplers but when you order you will probably need two couplers for your project=order TWO COUPLERS

Works great, hard to find one in white! NOTE: This size also has another measurement that is referred to as 4" Concrete x 4" Cast Iron/Plastic.
