Transtibial prosthetic liner UltraSeal Gel Liner

transfemoral

Product description
ALPS UltraSeal Gel Liner is a prosthetic gel liner featuring a single sealing band available in three ring heights (High, Low, Ultra Low). The internal OptiGel surface provides close conformity and cushioning to the residual limb while the outer premium fabric limits vertical stretch and pistoning. Available for above-knee (AK) and below-knee (BK) prosthetic fittings and offered in locking (pin) and cushion (vacuum/hypobaric) suspensions.

Key benefits

• Reduced constriction: outer premium fabric with differentiated stretch combines strength and comfort to reduce pressure points.
• Gel sealing technology: OptiGel inner surface offers smooth, soft contact for improved fit and skin compatibility.
• Suspension flexibility: available in Locking (distal pin/locking matrix) and Cushion (hypobaric) options to suit clinical needs.
