High performance seals can be designed and manufactured by AFT wherever durability and resistance to chemicals and temperature fluctuations are the norm. Seals can be provided in PTFE and filled PTFE materials designed to give increased performance.

AFT can manufacture seals for most applications. PTFE materials can be selected to meet the particular application and the design can be tailored to suit.

Elastomeric Energiser Material
Selection depends wholly on the service conditions, specifically temperature and media. Options include Viton, Nitrile, Silicone, EPDM and Perfluoroelastomer also Known as Kalrez.

Spring Energiser Material
These would typically be Stainless Steel but for more aggressive environments or to meet NACE approvals, Elgiloy, Hastelloy and Inconel may be selected.

Jacket material is not restricted to just PTFE
Commonly Virgin, Carbon, Graphite, Glass/Moly and Bronze filled PTFE would be used but for applications using non hardened running surfaces Ekonol filled PTFE would be recommended. There are many special blends of PTFE for specific high performance uses and UHMWPE is also commonly used. All material selection is specific to application.

AFAB/R rubber energised PTFE piston and rod seals
		These are suitable for use in both single and double acting applications. Typical use would be in reciprocating applications for hydraulic and pneumatic use. Recommended materials would include Bronze filled PTFE, CCA/Moly filled PTFE, Carbon/Graphite filled PTFE and Glass/CCA filled PTFE.
AFBB/R rubber energised PTFE piston and rod seals
		These are suitable for use in both single and double acting applications. They are designed to replace standard O-rings where friction reduction and/or increased seal life is required. Typical use would be in reciprocating applications for hydraulic and pneumatic use. Recommended materials would include Carbon filled PTFE and Moly/CCA filled PTFE.

AFVB/R Spring energised PTFE piston and rod seals
		This design of seal utilises a PTFE jacket with a ‘V’ type metallic spring energiser. The seal is only suitable for single acting applications where a very high performance seal is required. Ideally suited for reciprocating applications but can also be used for slowly rotating and oscillating applications. The seal is suitable for both rod and bore configuration.
AFVR-R Spring energised rotary shaft seals
		This design of seal utilises a PTFE jacket with a ‘V’ type metallic spring energiser. Specifically suited to single acting rotary applications.
AFCB/R Spring energised PTFE piston and rod seals
		This design of seal utilises a PTFE jacket with a helical metallic spring energiser. ‘C’ series seals are ideally suited for very high pressure applications. The seal is only suitable for single acting very low speed and static applications where a very high performance seal is required. The seal is suitable for both rod and bore configuration.
AFCI/E Spring energised PTFE face seals
		This design of seal utilises a PTFE jacket with a helical metallic spring energiser. ‘C’ series seals are specifically for use in high pressure single acting static applications. The seal can be made to suit either internal or external configuration.

		Rotary shaft seal with O-ring outer sealing.
		O-ring energised rod seal with angled back up ring.
