Goal: To establish whether
commercially available resilient
mechanical bulkhead pipe transits
are suitable for US Navy
applications and quantify the
benefits for their use.

Steps 1-3 are to size the Roxtec seal, lubricate the sleeve and seal, and fit the seal onto
the pipe.
Step 4 is for tightening of the bolts using an Allen wrench

Task 3 – Fire, Smoke, and Toxicity Qualifications
• MIL-DTL-24705B, “General Specification for Penetrators, Multiple Cable, Electric Cable”
• NSTM 505 extension to pipe transits
• RS and RS OMD pipe transits are equivalent to their cable transit counterparts
• Fire stop test performed for RS and RS OMD seals as cable transits
• SPM seals differ from the RS and RS OMD and have not been qualified.
• For any of the ROXTEC products to become qualified for use on Navy ships, a letter to request approval for use would have to be sent to NAVSEA.

Task 6 – Final Evaluation and Recommendations
NNS recommends the RS seal and the RS OMD seal as the best alternatives for Navy shipboard use.
RS Seal
- Split design for easy
installation/replacement
- Pipes must be centered
during assembly
- Requires a Roxtec
specific sleeve
RS OMD Seal
- Split design for easy
installation/replacement
- Can be used with sleeves not
manufactured by Roxtec
- Pipes must be centered
during assembly
SPM Seal
- Complete no-weld solution
- Single piece design
- Installation limited to
thickness of the bulkhead
- Requires further testing
for fire stop test

Task 6 – Final Evaluation and Recommendations
Recommended Further Evaluation
• Shock and Vibration testing needs to be completed
• Service Life – need for life-cycle testing
• Structural concerns
• Thermal Insulation
