Ships complete with a 20.0 oz. black anodized aluminum retainer secured via a precision-machined aluminum bezel. The standard configuration for demanding aerospace dispensing operations — black anodized finish delivers superior corrosion resistance and durability for extended service life in the most demanding production environments.

The responsive trigger mechanism provides precise control over material flow — allowing operators to apply exact amounts of material exactly where needed, whether as individual drops, measured shots, or continuous beads. Flow is governed by material viscosity, air pressure, orifice size, and trigger duration for complete application versatility.

The ergonomic design incorporates a metal multi-axis swivel air fitting compatible with hose assemblies available in 5ft and 10ft configurations. Connection options include Aro, Hansen, Schrader air fittings, or universal ¼" female fittings for alternative air supply systems — ensuring seamless integration with existing production infrastructure.

The removable ergonomic black handle provides enhanced clearance and maneuverability for operations in space-restricted areas — without sacrificing dispensing control or application precision. Easily removed and reattached to adapt the tool to challenging workspace configurations across diverse aerospace manufacturing scenarios.

Engineered for durability and precision — robust construction combining premium metals and high-performance engineered plastics designed to withstand demanding production environments. Built for the rigors of aerospace manufacturing where reliability and consistent performance are non-negotiable.

When paired with PPG Industries' Semco® precision-molded cartridges, plungers, nozzles, sem-luer adapters, and sem-needles, the Model 250-A delivers unmatched dispensing accuracy — ensuring the exact amount of material is dispensed at the precise location required for your most demanding precision dispensing requirements.

Connect hose assembly to a regulated compressed air source — select Aro, Hansen, Schrader, or ¼" universal fitting to match your air supply

Load the 20.0 oz. Semco® cartridge into the retainer — place loaded retainer onto adapter assembly

Thread the precision-machined aluminum bezel onto the adapter assembly until tight — secure, rattle-free attachment

Depress trigger — air pressure pushes against plunger for precise drops, measured shots, or continuous beads at exact locations

Unscrew bezel, remove disposable cartridge and nozzle — dispose per local regulations and material safety data sheet

The gold standard for aircraft structural sealing, fuel tank sealant application, and potting compound dispensing in MRO and manufacturing environments where precision is non-negotiable

High-volume production sealant and adhesive dispensing for demanding manufacturing environments requiring consistent, controlled, and repeatable material application
