Claim 1
Independent Claim
322 words
An insulating gasket adapted for use in providing a leak free coNnection between a first conduit means and a second conduit means which are secured by a fastening means, said first conduit means having a larger inner diameter than the outer diameter of said second conduit means and adapted to receive at least a portion of said second conduit means, said first conduit means having an inner wall which is tapered inwardly from the end of said first conduit means adapted to receive said gasket; said gasket consisting essentially of a tubular sleeve and a plastic, nonelastomeric skirt; said sleeve being made of an elastomeric, insulating material having an outer wall, an inner wall and two ends; said sleeve being adapted to be received within said first conduit means for at least a portion of the length of said sleeve; said sleeve being adapted to receive said second conduit means whereby a portion of the outer wall of said second conduit means is covered by said sleeve and a portion of said sleeve covered second conduit means is disposed within said first conduit means; said skirt comprising an outer wall, an inner wall and first and second ends; said skirt being substantially smaller in length than the length of said sleeve and said outer wall of said skirt being sloped inwardly in a direction from said first end toward said second end; said skirt being positioned on said sleeve intermediate the ends of said sleeve with said second end of said skirt being adjacent said tapered inner wall of said first conduit means; and said fastening means being adapted to be positioned adjacent said first end of said skirt whereby, upon securement of said first and second conduit means, said sloped wall of said skirt contacts said tapered wall to create a force component along the radial axis of said second conduit means sufficient to cause deformation of said second conduit means.

Claim 3
Dependent Claim
15 words
The insulating gasket as recited in claim 1 wherein said skirt is made of nylon.
Claim 4
Dependent Claim
15 words
The insulating gasket as recited in claim 2 wherein said sleeve is made of rubber.
Claim 5
Dependent Claim
29 words
The insulating gasket as recited in claim 3 wherein said plastic skirt has a coefficient of friction which is substantially less than the coefficient of friction of said sleeve.
Claim 6
Dependent Claim
28 words
The insulating gasket as recited in claim 1 wherein said outer wall of said skirt is accurately shaped from said first skirt end to said remaining skirt end.
Claim 7
Dependent Claim
262 words
An insulating and compressive gasket assembly for sealing, insulating and securing a connection of a first conduit means and a second conduit means, said assembly comprising: a first and second conduit means, said first conduit means having an inner diameter larger than the outer diameter of said second conduit means; a gasket comprising a substantially tubular sleeve made of a flexible, insulating material, and having an outer wall, and inner wall and two ends; a skirt consisting essentially of a plastic, nonelastomeric material positioned on said outer wall of said sleeve; at least a portion of said second conduit means being received by and enclosed by said inner wall of said sleeve; at least a portion of both the outer wall of said sleeve and said enclosed second conduit means being received by said first conduit means; said skirt being substantially smaller in length than the length of said sleeve and comprising an outer wall, an inner wall and first and second ends; said outer wall sloping inwardly in a direction from said first skirt end toward said second skirt end; a fastening means for securing said first and second conduit means; said fastening means being adjacent said first end of said skirt while said second skirt end is adjacent said tapered wall of said first conduit means; and whereby upon securement of said first and second conduit means, said sloped wall of said skirt contacts said tapered wall to create a force component along the radial axis of said second conduit means sufficient to cause deformation of said second conduit means.
Claim 8
Dependent Claim
262 words
An insulating and compressive gasket assembly for sealing, insulating and securing a connection of a first conduit means and a second conduit means, said assembly comprising: a first and second conduit means, said first conduit means having an inner diameter larger than the outer diameter of said second conduit means; a gasket comprising a substantially tubular sleeve made of a flexible, insulating material, and having an outer wall, and inner wall and two ends; a skirt consisting essentially of a plastic, nonelastomeric material positioned on said outer wall of said sleeve; at least a portion of said second conduit means being received by and enclosed by said inner wall of said sleeve; at least a portion of both the outer wall of said sleeve and said enclosed second conduit means being received by said first conduit means; said skirt being substantially smaller in length than the length of said sleeve and comprising an outer wall, an inner wall and first and second ends; said outer wall sloping inwardly in a direction from said first skirt end toward said second skirt end; a fastening means for securing said first and second conduit means; said fastening means being adjacent said first end of said skirt while said second skirt end is adjacent said tapered wall of said first conduit means; and whereby upon securement of said first and second conduit means, said sloped wall of said skirt contacts said tapered wall to create a force component along the radial axis of said second conduit means sufficient to cause deformation of said second conduit means.
Claim 9
Dependent Claim
17 words
The insuLating and compressive gasket as recited in claim 6 wherein said skirt is made of nylon.
Claim 10
Dependent Claim
16 words
The insulating gasket assembly as recited in claim 6 wherein said sleeve is made of rubber.
Claim 11
Dependent Claim
29 words
The insulating gasket assembly as recited in claim 6 wherein said outer wall of said skirt is accurately shaped from said first skirt end to said remaining skirt end.
