A ball joint comprising
- a first tubular member having an enlarged inner diameter at one end thereof with an internal groove,
- a seal ring in said internal groove,
- a second tubular member having a partial external spherical surface on one end thereof,
- the spherical surface of said second tubular member being positioned within said one end of said first tubular member in sealing engagement with said seal ring,
- a first flange having an inner diameter sufficiently large to allow installation and removal of said second tubular member therethrough,
- means connecting said first flange to the other end of said second tubular member from said spherical surface, and
- means interconnecting said first tubular member and said first flange whereby relative pivoting between said tubular members is maintained about the center of said spherical surface,
- said second tubular member being removable and replaceable through said first flange without disconnecting said interconnecting means when said first flange is free of connections other than said interconnecting means.
