摘要: A self-sealing pipe thread provides a connection for internally pressurized PVC pipes without the necessity of using sealant, O-rings, or gaskets. The holds pressure inside and does not let gas liquid to come in contact with any other threads. sealing is provided by tangential intersection between flat annular surface integrally formed on head an line edge defining ring step base outside thread.
