RTS Companies Inc. PCO 50-Gallon Rotomolded Polyethylene Tank — Vented Cap & Siphon Elbow

The RTS Plastics PCO 50-Gallon rotomolded polyethylene tank is a durable, vented-cap storage and transport solution for water and non-flammable liquids with molded grad strips and a siphon elbow for complete drainage.

Built by RTS Companies Inc., this PCO-style tank combines seamless rotomolded construction, molded-in gallon markings, and user-focused fittings to make liquid handling straightforward whether you’re mounting it on a vehicle, installing it in a utility trailer, or using it as a stationary reservoir. The tank ships with a vented cap to prevent vacuum lock, a pre-installed bulkhead fitting for fast hose or valve attachment, and strap grooves molded into the body for secure installation. Constructed in the USA from impact- and chemical-resistant polyethylene, it’s designed to resist weathering and hold up to everyday use.

How does this tank make pumping and drainage easier?

The PCO 50-Gallon tank includes features that streamline fluid transfer so pumps work more reliably and the tank drains fully. The vented cap maintains airflow to prevent vacuum buildup during pumping and the included siphon elbow helps evacuate liquid from low points.

• Vented cap for uninterrupted pump suction and reduced vacuum lock
• Siphon elbow included for near-complete drainage
• Pre-installed bulkhead fitting for quick hose or valve hookup

What makes the tank durable for outdoor and transport use?

This tank is rotomolded as a single seamless part, which improves impact resistance and eliminates weak joints. Polyethylene resists UV, chemicals, and temperature changes better than many alternatives, and molded strap grooves allow firm mounting during transit.

• Seamless rotomolded polyethylene construction for strength
• Molded strap grooves for secure mounting during transport
• Engineered to resist common weathering and chemical exposure

How do you monitor and connect fittings quickly?

The tank’s molded-in grad strip gives an immediate visual of the remaining volume while the pre-installed bulkhead fitting reduces installation time for pumps, valves, and hoses. This combination minimizes guesswork and gets systems online faster.

• Molded-in gallon markings for fast level checks without gauges
• Pre-installed bulkhead fitting cuts plumbing time and leak points
• Standard PCO opening compatible with common pump adapters
