Technical Information
This black self-fusing silicone tape meets both MIL-I-46852 and A-A-59163 Class 1 Type II military specifications, making it one of the most broadly qualified self-fusing silicone tapes for defense and aerospace electrical insulation applications. The dual-specification qualification provides procurement flexibility across programs specifying either document. At 0.020″ thickness on a 36-foot roll, it provides ample material for wire harness sealing, connector boot replacement, cable splice insulation, and hose fitting protection in aircraft and ground vehicle electrical systems.
Why Choose MIL-I-46852 / A-A-59163 Class 1 Type II?
- Dual Mil-Spec Qualified — Meets both MIL-I-46852 and A-A-59163 Class 1 Type II for broad program use
- Standard 0.020″ Thickness — Optimum balance of conformability and insulation build per wrap
- 36′ Roll Length — Ample material for complete wire harness and connector sealing tasks
- Adhesive-Free Self-Fusion — Bonds to itself only — no residue, no surface preparation
- Black Electrical Identification — Standard black color for military electrical insulation applications
Frequently Asked Questions
Q: What specifications does this black silicone tape meet?
A: This tape meets both MIL-I-46852 and A-A-59163 Class 1 Type II military specifications for self-fusing silicone electrical insulation tape.
Q: What is the MPN for this dual-spec silicone tape?
A: The Manufacturer Part Number (MPN) is AA59163-1-II-0-020-1-000BLK.
Q: What is MIL-I-46852 specification?
A: MIL-I-46852 is a military specification for insulating tape, electrical, self-fusing, covering performance requirements for use in military aircraft and ground vehicle electrical systems. It has largely been superseded by A-A-59163 but remains referenced in legacy programs.
Q: How does self-fusing tape provide electrical insulation?
A: When stretched approximately 50–75% and wrapped with at least 50% overlap, self-fusing silicone tape layers fuse together under pressure to form a solid, void-free silicone rubber mass that provides high dielectric strength electrical insulation around the conductor or splice.
Q: What is the correct wrapping technique for self-fusing silicone tape?
A: Stretch the tape to approximately 50–75% elongation, apply with 50% overlap between successive wraps, and ensure hand pressure is applied throughout to initiate self-fusion. Always start and end with a full, unstretched anchor wrap for secure termination.
