Questions & Answers

Is this a genuine original part?

This is a premium SEAFLO 51 NEW Series product, manufactured to the highest standards. 4Boats is an authorized distributor of Seaflo aftermarket equipment.

Does this pump require an accumulator tank?

While an accumulator tank is always beneficial for very fine flow control, the 51 Series features an internal bypass that manages pressure fluctuations internally, meaning it can be used effectively without one.

Can it be used with salt water?

Yes, the materials used (EPDM/Santoprene) and the waterproof/dustproof sealing make it suitable for both fresh and salt water applications.

Do away with vet teeth cleaning. Great product.
Color: Monster Bone, Size: XX-Large
My large dogs love these. It keeps their teeth clean and no tarter or cavities after 4 years of using. It has even helped an adopted older dog to have stronger teeth. They don't ingest anything, so safe to chew on.

Great for chewers
Color: Knuckle Bone, Size: XX-Large
I have a 13 month old 56 lb boxer/rottie mix who is a medium chewer and this bone is great for him. No splintering, doesn't make a mess, and hard enough to make him work without any danger of him breaking teeth, getting cut, or choking. We gave it to him a couple of weeks ago and based on wear I'm confident it will last him a long time (many months at least). I was a little hesitant about giving my animal a product that contained nylon, but after a scary experience giving a rawhide bone to a previous foster dog, I was told this was a much safer option and now I agree. This bone is very dense and very hard, so it makes an awful noise when my dog drops it on my hardwood floor. We are also careful to make sure he doesn't drop it on our bare toes, because that would be quite unpleasant. Be aware that the chewed edges also get really rough because of the way the bone wears, so they can become a magnet for dog hairs or fabric threads. This hasn't been a problem for us (we just encourage our pup to chew it on his bed and take it away from him when we are watching a movie so the noise isn't bothersome), but it is good to know. Update: We've had Winston for 5 months now and in that time he has gained 5 lbs of muscle. He loves his Nylabone! It is still going strong and I think he will be able to use this well through his one year adoptiversary. The only issue we have with this bone is that the edges can get sharp and sometimes will cut his mouth. He doesn't notice and just wants to keep chewing, but we usually take the bone away at that point for a bit. My boyfriend has taken the bone and used a power sander on it a few times now to remove all the sharp edges. We only have to to in once every couple of months but it makes a big difference.

The best toy my dog has
Color: Monster Bone, Size: XX-Large
Our lab mix is a very ambitious chewer - forget retrieving... he seems to think his "job" in life is to destroy things with his teeth. He's very methodical about it; he'll chew and chew and chew, targeting the object's weakest points, until all that remains is a littering of coin-sized remnants. He even started to make progress on his heavy duty black Kong within about a week. By the time he was about 8 months old, we figured out that the only toys he can be left alone with are the ones made by Nylabone. He has all their models: dinosaurs, rings, small bones, and branches. These Nylabone toys are a hard plastic that chips off in tiny little shards. He's happy because he feels like he's making progress (even though it takes him a long time to do so) and we're happy because the toys last a relatively long time and he can't swallow anything that might hurt him. He does leave tiny plastic shavings on the carpet, but we have to vacuum a lot anyways because of his fur, so it's not a big deal. Of all his Nylabone toys, this is the best (and probably his favorite of the bunch). He really likes the size - just right for him to prance around with and show off. Although he's had it for four months, it's still smooth enough in the middle that we can hold it for him comfortably, and it's retained its original shape (unlike dinosaur and branch). If we could just train him not to drop this on our feet when he wants attention(it weighs a few pounds and has gotten a bit pokey on the ends)this would be the perfect toy.
