got a 1.30 inch inside diameter hose. is UC33 the right size projectile for it?
Question by: Duane S on Feb 24, 2026, 7:56 PM
Fit is based on the inside diameter, and this projectile is sized for about a 1.30 inch I.D. The listed I.D. for UC33 is 1.2992 inches, so it matches up with a 1.30 inch hose I.D. for cleaning.

trying to figure out if these work on air conditioning and refrigeration lines or if they are strictly for hydraulic stuff
Question by: Hank K on Aug 7, 2025, 4:08 PM
Refrigeration and air conditioning lines are perfect applications for these. The system clears out those tubes along with heat exchangers, food and beverage lines, fuel lines, and standard hydraulic or pneumatic setups.

projectile sizing kinda confuses me, got a hose with a 1.30 inch ID and just wanna make sure this is the right one to grab
Question by: Gene S on Oct 15, 2025, 5:52 PM
For IDs of 2 inches or less, the projectile's outer diameter should run about 20% larger than the inner diameter you're cleaning. This one is built specifically for a 1.30-inch ID, so the sizing math is already done for you. One thing worth knowing: if the projectile won't leave the nozzle, it's too big, and if it passes through without resistance it's too small. Should a projectile get stuck mid-run, fire an empty discharge from the opposite end to push it back out.

Reckon these projectiles would work for cleaning out some hydraulic lines on my tractor? They're about that size.
Question by: Floyd F on Oct 2, 2025, 7:07 AM
They're designed for hydraulic and pneumatic lines, so they should do the job just fine, provided your lines are close to that 1.30-inch ID.
