883-030 Threaded Nipple

Extend the length of your pipes or connect two fittings using Spears 883-030 Threaded Pipe Nipple. It features 3/4" MNPT threaded connections on each end and measures 3 inches long. Molded Schedule 80 PVC construction has thicker walls than standard PVC, which means it can withstand industrial applications and heavy use. Unlike conventional metal fittings, it won't corrode, rust, pit, or scale which delivers a much longer lifespan.

Which Threaded Joint Sealant Should Be Used with the Spears 883-030 Nipple?

Spears recommends a compatible paste. Paste-type thread sealants fill the threads better than tape. Application is less critical as long as the sealant is compatible with the particular plastic being used (in this case, Schedule 80). Some "pipe dopes" and pasts can cause chemical stress cracking. Spears BLUE 75 thread sealant has been specially formulated and tested for use with Spears plastic piping components.

The Problem with Using TFE Tape Sealants

TFE tape sealants require special attention on application. Failure to follow the recommendations below can result in female thread breaks due to excessive tape use, difficult assembly due to insufficient tape, leaks due to failure to cover starting threads, and leaks due to incorrectly applied tape that bunches at the thread entrance. Since TFE tape is a very good lubricant, care must be taken to not overtighten taped joints.

Recommendations if you MUST use TFE Tape

• Wrap tape in the direction of the threads (clockwise for right-hand thread). For head adaptors, use only 2-3 wraps of tape and tighten to specified torque. For female adapter transition to metal pipe, use ONLY 5-5 1/2 wraps of tape.
• For joint assembly, tighten threaded joints 1-2 turns beyond finger tight. Avoid backing up the wrenched assembly. Do NOT overtighten.
• Hold end and pull tape tight into threads.
• Use TFE tape sealant with a minimum thickness of 2 1/2 mil.
• Always cover the end of the fitting at the start to prevent thread seizing prior to proper joint makeup

Tips

• Tape sealants are more susceptible to improper installation
  Paste sealants are more likely to contain incompatible chemicals
• Either type -paste or tape- must be properly used, but NEVER use both
• Do not use paste or tape on gasket sealed head adaptors
