Thread Removal - some fiberglass (long form) threads may require removal (using hacksaw) for proper sealing with steel 8rd (short form) connections. Most steel equipment and steel changeovers are prepared with short form 8rd threads. The steps prior to thread removal are as follows:
1. Chase the steel connection with a steel nipple.
2. Dry fit the fiberglass to steel connection.
3. If the connection seizes up premature to full engagement, then the steel is probably short form. Use Table 4.8 for thread removal from front of the fiberglass male.
