Multi-purpose spray 5L TEC 5 Viton, blue-black cap

The 5 litre chemical sprayer TEC 5 Viton holds 5540 ml in total and 4430 ml of usable liquid. EPOCA builds the unit in Italy for repeated chemical spraying work. Viton seals handle contact with aggressive liquids. A safety valve releases pressure automatically above 3 bar. The reinforced PP pump shaft drives the compression stroke.

A detachable spray handle lets the operator work away from the tank. The 1.4 m hose and the 40.5 cm plastic lance reach into corners and under machinery. An adjustable shoulder strap of 120 cm carries the tank during longer rounds. The nozzle produces a 110° fan pattern for even coverage. A wide stability base keeps the filled tank from tipping on a workshop floor. The blue-black cap marks this Viton version apart from the NBR and EPDM models of the same TEC 5 range.

5 litre chemical sprayer TEC 5 Viton: capacity, pressure and sealing

Tank volume and pressure control

Nominal volume is 5540 ml, while 4430 ml remains available for liquid once air space is kept free. Pressure builds through a manual pump with a reinforced PP shaft. Working pressure is capped at 3 bar. Above that level the integrated safety valve vents automatically, which limits over-pressurisation of the tank during pumping.

• Nominal volume: 5540 ml
• Usable volume: 4430 ml
• Maximum pressure: 3 bar
• Pressure safety valve with automatic release
• Pump shaft in reinforced PP
• Wide stability base against tipping

The base widens at the bottom so the tank stands upright on uneven shop floors. Operators can set the sprayer down between passes without holding it. Filling to the usable mark leaves room for air compression. Keeping within the 3 bar limit maintains a steady spray pattern and reduces pumping effort during long sessions.

Viton sealing and chemical resistance

Sealing uses Viton gaskets throughout the pressurised path. Viton is chosen where fluids attack standard rubber seals. The sealing set limits leakage at the cap and the pump, so pressure stays inside the tank. Within the TEC 5 family, the Viton version is identified by the blue-black cap, while other versions use NBR or EPDM seals.

• Seal material: Viton
• Cap colour coding: blue-black
• Chemical-resistant tank construction
• Detachable spray handle
• Nozzle with 110° fan spray effect

Match the seal material to the liquid before each job and check the chemical data sheet. Rinse the tank, hose and lance with clean water after use. Residues left in the nozzle can dry and distort the fan pattern. Store the sprayer depressurised, with the cap loosened, to keep the gaskets from taking a permanent set.

Lance, hose and carrying accessories

The supplied kit extends working reach beyond arm length. A plastic lance of 40.5 cm carries the nozzle to the target surface. The hose measures 1.4 m, so the tank can stay on the ground while spraying. A shoulder strap adjustable up to 120 cm supports the tank when the operator moves between stations.

• Plastic lance: 40.5 cm
• Flexible hose: 1.4 m
• Adjustable shoulder strap: up to 120 cm
• Separate spray handle for one-hand operation

Together these parts cover overhead edges, low plinths and areas behind equipment. The strap shifts tank weight to the shoulder during walking rounds. The separate handle keeps triggering simple while the other hand steadies a part. Replacement of the lance or hose is straightforward because each part connects to the handle.

Common applications

Typical use covers workshop and facility cleaning tasks with chemical solutions. Operators apply degreasers to machine frames, floors and engine parts. The unit also suits foam or detergent application in vehicle washing bays. Agricultural and horticultural users spray plant protection liquids over small areas. Maintenance teams use it for disinfectant application in production rooms, warehouses and animal housing. The 4430 ml working volume covers medium-sized areas between refills.
