1997 explorer 4.0 sohc
I have a 97 ford explorer xlt 4.0 sohc. I ordered new injector adapters part number F77Z-9G512-AA because my old ones were cracked and brittle. I found out while doing my intake manifold gaskets. My question is are they supposed to be plastic? My originals seem like a hard rubber and the new ones are plastic which i feel like is not going to seal very well. These are the ones i ordered https://www.amazon.com/gp/product/B07KFYW3LS/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
 






They are plastic or nylon that are hard to.
