Sealey Vs404 Oil And Brake Fluid Inspection Syringe 200Ml

I would have given this product 5 stars, but for the fact that the first one that arrived had a faulty valve. The replacement arrived quickly though.In my opinion, the best way to bleed motorbike brakes is to reverse bleed them i.e pump the brake fluid in through the caliper nipple. Some people try to do this with the small, free, syringes that you can get from a pharmacy. However, the problem is in topping up the small syringe during the process - and letting air in. It can be done, but it's a hassle. This syringe has ample capacity to manage without re-filling. Ideal for the task. Glad I bought one.

The one I received came in a Sealey box, but is not completely clear like the picture. Any hopes of "inspecting" fluids whilst still in the syringe are limited. For comparison, the plastic is about as see through as a 2 litre milk carton. It will need cleaned before first use as I have no idea what kind of gel/lubricant has been used on the seals initially. Whatever it was, there was plenty of it.The internal seals look like quite substantial, solid round grey silicone rings at first. Closer examination shows them to more of a "C"shape which allows liquid/dirt particles to get trapped inside them. There are also 8 recessed holes in the plunger end. Another nuisance when it comes to cleaning between fluid types.The hose on the end is easily replaceable 8mm OD which can be substituted for any length you choose. The fast fit connector ensures it does not fall out. The fast fit connector is held in place with a nut on the inside of the syringe, so easily replaceable too.The graduated markings on the outside allows volume measurement.It has its uses but is really time consuming to clean properly between fluid changes. Fine if you only ever plan to use it to draw fluids.

Did the job perfectly of replacing the brake fluid on my Vespa. I used the reverse method, pushing the fresh fluid up from the calliper bleed nipple to the master cylinder. A clip to retain the hose on the nipple would have be ideal but made do with a cable tie. Flushed it out afterwards with some petrol.

I purchased this to change the gearbox oil on a boat as access to the sump plug is very limited. It is easy to use and worked a treat. For the price I thought quality was very good, it feels solid and does what it was designed for. I would definately recommend.

Perfect as expected!!

Works as expected

Works Ok. Doesn’t really work well on motorbikes as the hose keeps falling off

It can be used for injecting liquid porcelain. I looked at a few before buying, but only used this one. It worked and can be cleaned.
