Overview

The Fernco SC425 400-425 mm shear banded coupling is designed to connect or repair low-pressure pipelines such as sewer, stormwater, and wastewater systems. The coupling is suitable for pipes with an outer diameter range of 400-425 mm. When compared with standard rubber pipe joiners, the shear banded coupling incorporates an additional reinforced stainless steel shear band positioned at the centre.

The Fernco shear banded coupling is made from flexible EPDM rubber or nitrile rubber and fitted with 316 grade stainless steel clamps, ensuring durability, elasticity, and stable long-term performance. The shear band helps protect the joint against corrosive environments, reduces the impact of shear forces caused by vibration, soil movement, or surface loading, and assists in maintaining consistent flow alignment inside the pipeline.

The Fernco SC shear banded coupling range is WaterMark licensed for use in Australia and can be used with compatible rubber bushes (sold separately) when connecting dissimilar pipe materials.

My 2 German shepherds love these good quality last a good bit
Size: Large (Pack of 1)
I buy these for my 2 German shepherds. My male is a heavy chewer and he will spend time with this everyday until he starts to wear it down or makes it into a makeshift shank and I replace it Last about 3-4 months for aggressive chewers. Highly recommend (keeps them from chewing my stuff)

The best bone you can get for pitbulls!
Size: Large (Pack of 1)
Can I give these more than five stars? Please?? They truly deserve more than that! I have bought these bones for the last 2 years for my pitbull mix, who is a very aggressive chewer. Her favorite thing to do is just lay and chew. These bones last FOREVER! She can lay there and chew all day long and they will last her MONTHS! It’s honestly amazing! These are the best bones we’ve ever given her and they are the only ones we’ll buy her! Not only do they last forever, they’re safe and natural too! Best product ever!

Great for aggressive chewers, but small mess
Size: Large (Pack of 1), Size: Large (Pack of 1)
He took it right away! It’s a great size. We’ll see how it holds up ONE MONTH UPDATE: (photo included) He loves it still! Still a bit messy but holding up great and he’s a aggressive chewer 1 WEEK UPDATE (photo update included) The bone is great. He loves it and it’s been holding up great. Our 8 month puppy is a super chewer and 60 lbs. the bone has signs of wear but nothing crazy. I went from 5 stars to 4 stars because whenever he chews the bone, the small tiny pieces of bone/wood go everywhere and they’re sticky/hard and make kind of a mess. But still would get this bone again and highly recommend

Made for aggressive chewers
Size: Small (Pack of 1)
My aggressive chewers are obsessed. This is one of the only chew toys that actually lasts for them. Always have to buy 2 so they each have their own
