SURE SHOT Filler Cap for Model A Sprayers Sur-Fil S-20F Quick-Connect — Chemical-Resistant Secure Seal

The Sure Shot S-118F is a replacement filler cap designed specifically for Model A sprayers that use the Sur-Fil S-20F quick-connect filling system, delivering a secure, chemical-resistant seal to minimize leaks and extend sprayer life.

When a worn or damaged filler cap causes drips, slow filling, or lost pressure, swapping in the S-118F restores reliable operation without replacing the entire sprayer. This cap is engineered for professional environments—workshops, detail bays, and industrial cleaning rigs—where durability and chemical resistance matter. It only fits Sure Shot Model A sprayers equipped with the Sur-Fil S-20F quick-connect system, so confirming compatibility before purchase avoids returns.

How does the S-118F improve filling and leak control?

The S-118F provides a tight, engineered seal that reduces accidental leakage during high-pressure spraying and transport. Its design channels fill flows cleanly through the Sur-Fil quick-connect interface for faster, cleaner refills. The cap’s fit and material selection focus on preventing chemical degradation that can cause vapor escape or seepage over time.

• Precisely matched threads and gasket seating for a snug fit.
• Resistant materials prevent swelling and cracking from solvents.
• Quick-connect design speeds refills and reduces splashing.
• Tight seal maintains internal pressure and reduces vapor loss.

Will the S-118F work with my existing sprayer setup?

This filler cap only fits Model A sprayers that use the Sur-Fil S-20F quick-connect filing system; it is not compatible with standard filler-cap sprayers. If your sprayer uses a different filler connection (for example, SUR-156 or P118), this part will not attach correctly. Verify the quick-connect style on your sprayer before ordering to ensure a proper match.

• Designed exclusively for Sur-Fil S-20F quick-connect interfaces.
• Not compatible with standard filler caps or other Sure Shot part numbers.
• Check your sprayer model and connector type before purchase.
• Easy swap—hand-tighten installation when compatible.

What chemicals and working conditions can the S-118F endure?

The S-118F is built from industrial-grade, chemically resistant materials suited to common cleaners, degreasers, and lubricants used in automotive and industrial settings. It withstands heavy use and repeated chemical exposure better than typical consumer-grade caps. Still, avoid prolonged contact with highly corrosive acids or unknown blends without confirming compatibility.

• Formulated to resist common solvents, detergents, and oils.
• Manufactured for repeated exposure in workshop environments.
• Durable under moderate pressure and temperature ranges found in service use.
• Not intended for untested, highly corrosive chemicals—consult material data if unsure.

How easy is installation and maintenance for the S-118F?

Installation is tool-free: hand-tighten the S-118F into the Sur-Fil S-20F quick-connect receiver until it seats. Routine maintenance is minimal—periodic inspection of the gasket and connection point keeps the cap sealing effectively. Replacing an old cap with the S-118F is a low-effort way to reduce downtime and keep sprayers in service.

• Tool-free, hand-tighten installation for fast replacement.
• Inspect gasket and threads periodically for wear or damage.
• Simple cleaning extends service life—wipe with compatible solvent if needed.
• Replacement recommended if cracking, warping, or persistent leaks occur.

Who is this for: The Sure Shot S-118F filler cap is aimed at professionals and serious DIYers who rely on Model A Sure Shot sprayers with the Sur-Fil S-20F quick-connect system.
