Trouble Shooting Airless Paint Sprayers

What happens here

The cleaned ball valve assembly is now ready to be reattached to the sprayer. Piston lube (also referred to as 'throat seal liquid' or TSL) is applied to the threads of the lower intake section before screwing it back onto the sprayer. This lubrication is vital as it prevents paint from drying and seizing the threads, making future disassembly easier and preventing corrosion. The intake tube, which features two O-rings, is also reattached. Lubricating these O-rings (with piston lube or silicone lube) is highly recommended to maintain their flexibility and sealing integrity, especially on older sprayers that might have hardened O-rings.

Goal: Properly reassemble the sprayer, lubricating key components for optimal function and longevity.

Tools and materials

  • Airless Sprayer — The main equipment being reassembled
  • Cleaning Rag — Wiping off excess lubricant or paint
  • Piston Lube — Lubricating threads and O-rings to prevent seizing and ensure smooth operation

keep cycling and losing its prime so now we got this thing all cleaned off you're going to begin putting it back together and prior to putting it back together you want to make sure this is all cleaned really well make sure it's all wiped off no paint on that and one of the things we like to do is just take piston moves so we got some piston move right here and I like to rub some piston lube on the threads in here the threads both sides and one of the things that we'll do that will help fight corrosion and it'll help keep it from from sealing or protein on there locking itself on there so we're just gonna put a little drop of piston lube on there and then thread it on and that is it also if there's any paint on there on the threads and all anywhere it's gonna help keep that paint from drying and sealing those threads on there and making it really hard to take this thing off because it's gonna be on there from we don't take them off that often so it's easy for that thing to just tighten itself on there it gets ease down there pro did on there over a period of time so just a little bit of piston Lube put some piston Lube right there you can also use throat seal which is the same thing whatever you are typically lubricating your piston with so we've got our piston right here we're lubricating those things on a daily basis so there we go got that on now we're just gonna put our intake tube back on gonna wipe that off it's just gonna push right in this intake tube also it has two little wings on there and those o-rings this is a fairly new sprayer it's not brand new but we use it for a few x-series and I believe I think we haven't had it that long but you know those o-rings right now that they're nice and soft lubricated but you can also use some piston Lube or something to lubricate those or even some some lube for like silicone lube to make sure those things are lubricated after about a year so I probably lubricate them if I took this thing off again but we didn't need to do on the nice and soft brand-new so there we go tip that thing back up and I would assume this thing's gonna fire back up and be good to go if not then we would continue the troubleshooting process from there but what do you think like what percentage of the time that we run into these issues with it not priming is that the issue typically that's going to be the issue usually we're using something like usually we'll see in our next earier paint that dries really fast and it'll be a hot day…
