The Bobcat B419 is the largest orifice in the 40° Bobcat group — a 0.019” orifice delivering approximately 36 oz/min at 1000 PSI in the same 8” production-width pattern as the B413. It’s the configuration for operations running heavier materials where the 0.013” or 0.015” orifice doesn’t deliver enough material per pass to keep pace with production requirements, or where the coating viscosity is high enough to require a larger opening for consistent atomization.

At ~36 oz/min, the B419 delivers more than twice the fluid of the B413 at the same pressure and fan geometry. This is significant for high-viscosity industrial coatings, heavy primers, thick enamels, and other materials that are at the upper end of what the Bobcat system handles — where orifice size rather than fan angle is the primary selection variable.

The 40° angle keeps the efficient 8” production fan for components and panels. If you need the same high output over a wider surface, the B619 offers 0.019” at 60° for a 12” pattern. Call or text 586-210-0555 to confirm the right orifice for your material viscosity before ordering.

Fluid Tip

36-419

0.019” orifice · 40° angle · ~8” pattern

Largest orifice in the 40° Bobcat group — ~36 oz/min at 1000 PSI for heavy primers, high-solid coatings, and thick industrial enamels at production 8” fan width. Field-replaceable tip.

Air Cap

26-101

AAA HVLP air cap · ≤18 PSI at handle

Same air cap as all Bobcat configurations. At 0.019” with heavier materials, the AAA air assist helps achieve finer atomization than pure airless would produce at comparable fluid pressure.

Gun Type

AAA

Air Assist Airless · 1500 PSI max

Requires AAA pump (e.g., Peak 14:1). Heavier materials at 0.019” typically operate at higher fluid pressure — start at 500 PSI and increase until atomization is consistent.

Repair Kits

When do I step up to 0.019” from 0.017”?

Step up to B419 when your material at B417 (0.017”) shows inconsistent atomization, insufficient throughput for production rates, or requires more fluid pressure than expected to achieve a consistent pattern. Heavy-body industrial coatings and high-solid primers are the typical applications. Call or text 586-210-0555 — we’ll confirm the right orifice for your viscosity before you order.

What fluid pressure for heavy materials at 0.019”?

Heavier materials typically require higher fluid pressure for consistent atomization. Start at 500–700 PSI and increase until the pattern is consistent and fully atomized. Heavy industrial primers and high-solid coatings often run at 900–1200 PSI at 0.019”. Never exceed 1500 PSI maximum.

Is there a 0.019” option with a wider pattern?

Yes — the B619 uses the same 0.019” orifice at 60° for a 12” pattern, and the B719 uses 0.019” at 70° for a 14” pattern. All deliver the same ~36 oz/min flow rate — only the fan width changes. Call or text 586-210-0555 to confirm which is right for your substrate.

Can I swap tips without buying a new gun?

Yes — all 36-series tips are field-replaceable. Swap between 36-417 and 36-419 as your material mix changes without purchasing a new gun. Call or text 586-210-0555 to order replacement tips.

What repair kit does the Bobcat use?

10-137 covers routine maintenance — all o-rings and the seat. 10-138 is the complete kit adding the air valve assembly and needle seal cartridge. CET stocks both for same-day shipment. Most in-stock orders ship same day — stocked at C.A. Technologies’ Colorado facility.

Where can I find the Bobcat parts manual?
