Petroleum Containment, Inc. (PCI) continues to build its reputation for reliability with its line of fiberglass penetration fittings, what PCI calls its “Forever Fittings” because of their durability and long service life in underground petroleum containment systems.

Engineered for both new construction and retrofit applications, all PCI penetration fittings are compatible with single and double wall piping systems and built to maintain watertight integrity in harsh underground environments. Manufactured from 100% fiberglass, the fittings resist corrosion, fuel exposure, and ethanol blends that can cause traditional rubber or plastic fittings to deteriorate over time.

PCI’s TPP Series penetration fittings include integrated test ports that eliminate the need for separate test boots, simplifying installation, testing, and future maintenance. The TPT Series is commonly used in transition applications where contractors need reliable watertight seals while maintaining installation flexibility and accessibility within the sump.

For retrofit and service work, PCI’s STF Series split fittings allow contractors to install or repair systems without disconnecting existing piping, helping reduce downtime and labor in the field. The SRB Series provides dependable sealing around pipe penetrations to protect against water intrusion and environmental exposure, while the BSO Series is designed for larger openings and specialty applications that require additional flexibility without sacrificing containment integrity.

In addition to their durability, PCI fittings are known for short lead times and fast turnaround, helping contractors keep projects moving without long manufacturing delays.

Built for strength and longevity, PCI “Forever Fittings” are designed to help contractors and site owners avoid premature replacement costs while maintaining dependable performance throughout the life of the containment system.

All PCI penetration fittings are UL Listed 2447 and meet applicable industry compliance standards, including California Title 23 requirements.
