GRN® 34x45x7 FPM TC Double Lip Rotary Shaft Seal
GRN® 34x45x7 FPM TC is a double lip rotary shaft seal with nominal dimensions 34x45x7 mm. The seal is manufactured from FPM fluoroelastomer and features a primary sealing lip together with an auxiliary dust lip.
GRN® 34x45x7 FPM TC - Technical Characteristics
| Parameter | Specification |
|---|---|
| Brand | GRN® |
| Product type | Rotary shaft seal / radial shaft seal |
| Dimensions | 34x45x7 mm |
| Shaft diameter d | 34 mm |
| Outside diameter D | 45 mm |
| Height H | 7 mm |
| Material | FPM |
| Material type | Fluoroelastomer |
| Profile | TC |
| Construction | Double lip |
| Primary sealing lip | Yes |
| Auxiliary dust lip | Yes |
Dimensions
The nominal dimensions are:
d = 34 mm - shaft diameter
D = 45 mm - outside diameter
H = 7 mm - seal height
Complete dimensional designation:
34x45x7 mm
All three dimensions should be verified when identifying a replacement. A seal designed for a 34 mm shaft may be available with different outside diameters and widths.
TC Double Lip Construction
The TC configuration incorporates two functional lips.
The primary sealing lip operates dynamically against the rotating shaft and provides the main sealing function.
The auxiliary dust lip is positioned on the external side and provides an additional barrier against dust and other external contamination.
This double-lip construction is an important distinction when comparing GRN® 34x45x7 FPM TC with single-lip seals of the same dimensions.
FPM Fluoroelastomer
The specified material is:
FPM - fluoroelastomer
Material is an important part of the complete product identification:
34x45x7 + FPM + TC
A 34x45x7 NBR seal should therefore not automatically be considered technically identical to the FPM version.
Exact operating temperature limits, Shore hardness, maximum pressure and maximum shaft speed depend on the specific FPM compound and application conditions.
How the Seal Works
The seal is installed with its 45 mm outside diameter in the stationary housing bore.
The primary sealing lip operates dynamically against a shaft with a nominal diameter of:
34 mm
During shaft rotation, the primary lip maintains the dynamic sealing interface. The auxiliary lip provides an additional external contamination barrier.
During replacement, the shaft sealing surface should be inspected for wear grooves, corrosion, scratches or other damage that could affect the new seal.
TC Profile
For the international English product description, the profile is identified as:
TC
This provides a clear technical search entity:
GRN® 34x45x7 FPM TC
Profile terminology is not completely standardized between all seal manufacturers. Therefore, the TC designation alone should not be used to establish interchangeability with another manufacturer's product.
Selection and Interchangeability
When selecting an equivalent for GRN® 34x45x7 FPM TC, verify:
d = 34 mm
D = 45 mm
H = 7 mm
FPM material
TC double-lip construction
primary sealing lip
auxiliary dust lip
Identical 34x45x7 mm dimensions alone do not confirm complete interchangeability.
Material and lip configuration are particularly important when comparing FPM and NBR versions.

FAQ
What are the dimensions of GRN® 34x45x7 FPM TC?
The nominal dimensions are 34x45x7 mm: d = 34 mm, D = 45 mm and H = 7 mm.
What material is the seal made from?
The specified material is FPM fluoroelastomer.
Is GRN® 34x45x7 FPM TC a double lip oil seal?
Yes. The TC construction incorporates a primary sealing lip and an auxiliary dust lip.
What is the purpose of the auxiliary dust lip?
The auxiliary lip provides an additional barrier against dust and external contamination around the primary sealing area.
Is an NBR 34x45x7 seal the same as this FPM seal?
Not automatically. Although the dimensions may be identical, NBR and FPM are different elastomer materials and should be selected according to the requirements of the application.
What does TC mean in this product description?
TC identifies the double-lip configuration used for the international product description, with a primary sealing lip and an auxiliary dust lip.
Is every 34x45x7 TC oil seal interchangeable?
No. Dimensions, elastomer material, actual lip construction and application requirements should all be verified before substitution.
