Is there a repair kit for Poly B?
The straight answer
Not a kit as such: legitimate repairs use fittings certified for polybutylene, either push-fit conversion couplings or crimp transition couplings made to ASTM F1380, splicing in PEX or PE-RT.
The longer version
There’s no magic kit, and since new Poly B hasn’t existed since 1998, every repair is really a small transition to modern pipe: a rated conversion coupling or an ASTM F1380 crimp transition splicing in PEX or PE-RT. What to avoid is just as important: no glue, no standard push-fits, no torch near the plastic. The fittings and repairs guide is the full playbook.
