Product Number: JGBC1238
Leaking pneumatic joints and time-consuming thread sealing slow down any air system installation or repair. The Sealey JGBC1238 is a brass SuperThread straight adaptor designed for the John Guest® Pneumatic Coupling System, connecting 12mm OD pipe to a 3/8" BSP thread cleanly and reliably. The SuperThread design is compatible with BSP (parallel), BSPT (taper), NPTF, PF, and PT metal thread forms, giving broad compatibility across different systems and fittings already in use. A special polyurethane seal means no thread sealant needs to be applied the joint is airtight straight from fitting, saving time and eliminating the mess of PTFE tape or paste. Supplied as a pack of 2, this adaptor is a practical buy for installations where more than one connection point is needed. Cross-referenced to John Guest Speedfit® part RM011213.
