Replacement Sleeves for Pinch Valves: Maintenance Made Easy

The Rubber Sleeve – Our Know-How

Available colors: Black & pale

Additional grades available upon request

HO-Matic sleeves are made from specially developed elastomer compounds with high-strength fabric reinforcements. This ensures the high demands for robustness, elasticity, restoring force, and long service life are fully met.The highly elastic, pneumatically actuated sleeve reliably closes the product flow with only 2–3 bar differential pressure (depending on the elastomer quality). Thanks to its excellent resilience, it automatically returns to its fully open position as soon as the control pressure is released.

NR – Natural Rubber (FDA, ATEX)

The best choice for bulk solids. Excellent elasticity, very good mechanical properties, outstanding service life, highly abrasion-resistant, and strong restoring force after deformation.

Material Grades

NR (Standard): Black. Up to max. +80°C / available up to +90°C upon request

NR-L: Black, food-grade (FDA), up to max. +80°C

NR-LH: Natural rubber, food-grade, light-colored, up to max. +70°C

NR-LE: Black, electrically conductive for use in ATEX zones

Resistant to:

Mildly aggressive chemicals / Organic acids / Alcohols, salts

NBR – Nitrile Rubber (FDA, ATEX)

Essential for fuels, oils, and greases. Offers excellent resistance to mechanical and weather-induced wear, along with superior oil and fuel resistance.

Material Grades

NBR (Standard): Black. For fuels, oils, oil-lubricated compressed air

NBR-LH: Light/White, food-grade (FDA). For fatty food products, up to max. +80°C

NBR-LE: Electrically conductive for ATEX, up to max. +80°C

Resistant to:

fats, oils, gasoline / Solvents / Most common hydrocarbons

EPDM – Ethylene Propylene (FDA, ATEX)

The industry standard for hygiene and chemicals. Excellent heat resistance and high resistance to acids, alkalis, and hot water. Ideal for CIP/SIP cleaning processes. Features outstanding weather resistance and superior electrical insulation properties.

Material Grades

EPDM-L: Black, food-grade (FDA) and conductive (ATEX). Heat resistant up to +120°C / QSV +80°C

EPDM-LH: Light-colored, up to max. +100°C / QSV +80°C

EPDM-LE: Black, food-grade, electrically conductive, up to +120°C / QSV +80°C

Resistant to:

Ozone and weathering (UV) / Steam, hot water / Aggressive chemicals

FPM – Fluoroelastomer

The specialist for chemical-resistant applications. Engineered for highly aggressive chemicals, aromatic solvents, and high temperatures where standard elastomers would swell. Features exceptionally low gas permeability.

Material Grades

FPM: Fluoroelastomer, up to max. +100°C / QSV +80°C

Resistant to:

High heat resistance / Hydrocarbons / Many acids, animal and vegetable oils

CR – Chloroprene Rubber

Specifically renowned for its outstanding ozone resistance. Also offers excellent resistance to weathering and aging. Flame retardant and frequently used in outdoor installations. Features low air permeability and robust chemical resistance.

Material Grades

CR: Chloroprene rubber, up to max. +80°C

Resistant to:

Mild acids and chemicals / Ozone / Oils, greases

CSM – Chlorosulfonated Polyethylene

Specifically engineered for chemicals and oxidizing media. Offers good resistance to aging, weathering, and ozone, alongside low air permeability.

Material Grades

CSM: Chlorosulfonated polyethylene, up to max. +80°C

Resistant to:

Concentrated acids, alkalis / Ozone / Alcohols, alkalines, and hypochlorite solutions
