Oversized SRB Fiberglass Repair Penetration Fittings

PCI Oversized SRB Series Split Repair with Band Clamp Fittings restore watertight seals around existing piping and conduit penetrations. The larger profile is designed to eliminate the need to pair a standard SRB fitting with a separate BSO fitting in applicable repairs.
Built from 100% fiberglass and compatible with double wall containment systems, the Oversized SRB combines an 8-inch outside diameter with a split design for installation around existing lines.
Double Wall Compatible
Oversized SRB fittings are compatible with double wall containment systems.
Larger Repair Profile
The 8-inch outside diameter provides a larger bonding footprint at the sump wall, offering an alternative to a separate SRB and BSO combination where installation conditions allow.
Split Design for Repairs
The fitting assembles around existing piping or conduit, simplifying replacement of damaged or deteriorated penetration boots.
Band Clamp with Retention Rim
A stainless steel band clamp holds the fitting together while the epoxy cures. The retention rim prevents the clamp from sliding off during installation.
Misalignment Flexibility
Oversized SRB fittings accommodate angled pipe entries up to 20 degrees, providing flexibility when repairing existing penetrations.
Fiberglass Sleeve for Flex Pipe
Flex pipe models include a fiberglass sleeve. Bonded to polyethylene piping with PCI’s Clear Magic adhesive, the sleeve provides a fiberglass surface for bonding the repair fitting.
100% Fiberglass Construction
Corrosion-resistant fiberglass provides strength and a durable alternative to rubber or plastic penetration boots, supporting long-term performance during fuel exposure, including ethanol.
Field-Modifiable Design
Oversized SRB fittings can be modified in the field to simplify service work. Follow PCI’s installation guidance for modifications and bonding requirements.
