Triclamp fittings
Article number	Size	Description
E33208	1.5"	Tri-clamp process adapter for G1 aseptoflex vario
E33209	2"	Tri-clamp process adapter for G1 aseptoflex vario

Weld fittings
Article number	Description	Recommendation	Tank diameter	Wall thickness	Customer benefits
E30528	Weld adapter, 85mm dia.; concave form; 26.5 mm height; 6 mm rim height	For installation in tank heads and walls – recessed sensing face location	> 1.5 m	< 4mm	Recessed sensor location is better drainage when installed in tank head Flanged design adsorbs stresses during welding to keep sealing profile in tolerance Larger 85mm diameter is easier to weld
E30529	Weld adapter, 85mm dia.; convex form; 16.5 mm height; 6 mm rim height	For installation in tank bottoms, walls, larger tank diameters – protruding sensing face location better for drainage off sensing face	> 1.5 m	< 4mm	Protruding location is better for drainage in conical sections or on the bottom of tanks. Flanged design adsorbs stresses during welding to keep sealing profile in tolerance Larger 85mm diameter is easier to weld
E30130	Weld adapter, 50mm dia. straight wall	Standard weld adapter for tanks and pipes with 3A approval	> 1.5 m	4mm	Standard ifm adapter for experienced welders
E30149	Weld adapter, 60mm dia. straight wall	Standard weld adapter for larger tanks and pipes with 3A approval	> 1.5 m	4mm (or less)	Standard ifm adapter for experienced welders with smaller rim height for thinner tank walls

Weld accessories
Article number	Description
E30452	Weld mandrel recommended when installing any of ifm’s weld adapters on tanks or pipes to act as a heat sink and prevent warpage of the weld adapter.
E30160	Grinding protection for welding adapters to protect the sealing edge during weld seam cleanup.

Replacement o-rings
Article number	Material	Description	Supplied with:
E30054	EPDM FDA compliant	EPDM is the most common gasket material used in F&B applications and has a very good suitability with hot water / steam and both acidic / alkaline CIP fluids. This O-ring seals between the face of the process connection and the adapter.	Aseptoflex Vario adapter
E30123	FKM FDA compliant	FKM is very suitable for oil applications as there is minimum swelling even with mineral oils, and it is the most common material for industrial applications with excellent chemical and high temperature resistance.	Optional accessory purchased seperately
E30124	PEEK FDA compliant	PEEK is a more durable seal if devices are removed during the cleaning process, has universal resistance to chemicals, and is more stable than elastomers that become hard and brittle over time.	Optional accessory purchased seperately

Vent accessories
Article number	Description
E30139	Filter cover with tube fitting and vent tube that can be located in a protected and dry area.
E30467	Filter cover with rotatable push to connect fitting, additional plug-in filter cover, and vent tube. Recommended for applications where the end of the vent tube cannot be protected or where chemically demanding external cleaning is conducted.
