M&P Silicone-Seal-L 14.5cm Ø27.72

Self-tightening silicone rubber tubular gasket for Ø 5,3mm (.212”) Ø 7,3mm (.287”) or 10,3mm (.400”) or 12,7mm (.500”) cables, matched to any one of our related connectors and adapters. 

M&P-Silicone-Seal-L is a reliable tubular gasket that quickly seals the socket of the 50-ohm Antennas with the down lead cables, tightly, hermetically, and seamlessly. No flame or heat is required. 

One more application: you may use it inside an electrical cabinet to protect your connections from condensation. (Extension leads etc.) 

It is also handy as a strain relief, for increasing the tensile strength between cable and connector! 

The M&P-Silicone-Seal is factory expanded and assembled onto a removable supporting plastic core. The pre-stretched M&P-Silicone-Seal-L, as the core is unwound (from the inside), shrinks to form a thick and tight tubular gasket. 

Retains its resiliency and pressure even after years of aging and exposure to Ultraviolet rays, acids, condensation and harsh environments, with operating temperature range -60℃ ～ 90℃ (-76°F～194°F).

Flammability V-0 burning stops within 10 seconds on a vertical specimen, drips of particles allowed as long as they are not inflamed.

How to use: 

1) Once the connector has been assembled on the down lead cable to be connected, insert it inside the M&P-Silicone-Seal-L and make sure it will not slip away, down the cable (fix it temporarily with adhesive tape).  

2) After tightly screwing the two connectors together (never overdo it), press the M&P-Silicone-Seal-L firmly against the base of the Antenna protruding connector (the red arrow has to face down, the opposite way to the antenna socket). 

3) Then, while holding the M&P-Silicone-Seal-L in place, pull the protruding strip you can find inside one end of the white supporting plastic core (following the direction of the red arrow). Make sure the black silicone rubber placed over the plastic core, is well centered over the connectors to be protected, as this operation is not reversible. 

4) By continuing to pull the strip (which will come off forming a free spiral), the black silicone rubber, deprived of its plastic core support, will shrink, settling permanently on the cable and connectors, embedding them very tightly. 

This high-speed operation, which does not require any flame or heat, is completed, allowing you to operate in cold and windy environments or on top of towers without worries and assuring a professional and durable result!
