Diversitech HLP038 Foam Pigs 3/8 Inches 10 Pack

Product Description

The DIVERSITECH HLP038 is a 10-pack of 3/8-inch foam pigs designed for use with the Hilmor pipe launcher system. Foam pigs are consumable cleaning and sealing plugs used to clear debris, moisture, and obstructions from refrigerant lines, drain lines, and other small-diameter piping during installation or service. Each pig is sized at 3/8 inches in diameter to match standard tubing used in HVAC and refrigeration work. HVAC technicians and refrigeration service pros keep these on hand when pulling line sets or commissioning new equipment where tube cleanliness is critical.

These foam pigs are intended for use with the Hilmor launcher tool, making them a direct consumable replacement for field service kits. They are well-suited to residential and light commercial HVAC applications where 3/8-inch refrigerant or drain lines are being cleaned, dried, or tested before charging or startup. The 10-pack format supports multiple line clearing passes on a single job or restocking a service van.

Installation Notes

Foam pigs are installed and fired by a qualified HVAC technician using the Hilmor launcher tool per the tool manufacturer's instructions. Ensure the line is isolated and depressurized before loading a pig into the launcher. Do not use foam pigs on pressurized or charged refrigerant circuits. Recover any refrigerant and relieve system pressure before performing line cleaning procedures.
